The Continuum of Intelligence

The Continuum of Intelligence

What if the only purpose of the universe and the evolution of life was for the advancement of intelligence. Darwin was wrong, its not “survival of the fittest”, its “survival of the smartest”. The pursuit of advanced intelligence is our true purpose and will lead to answers to many of the biggest questions that currently challenge us. The Continuum of Intelligence is a roadmap for the journey towards advanced intelligence.

Abstract

The purpose of this article is to help provide a mechanism or index to measure the progress of the field of artificial intelligence towards artificial general intelligence, super intelligence and beyond. There is much uncertainty as to when these milestones will be achieved, but without a measure of progress towards them, it becomes even more difficult to determine when they might occur. This article will not only provide an index of the continuum of intelligence in which to measure our progress to achieving advanced AI, but will also give a considered view on some related topics, such as consciousness, dreaming and personality. Much has been written on these topics from physicists, mathematicians, neuroscientists, philosophers and phycologists, but here I provide a computer scientist’s perspective.

This article provides a preview of my book, by the same title, to be released in 2018.

Introduction

At almost every meeting and conference on AI most of us will at some stage be involved in a discussion on the definition of Artificial Intelligence. The reason for this is quite simple. As an industry we don’t have a universally accepted definition of AI [8]. Yes we have the Turing Test, but this only provides one milestone on the journey towards advanced artificial intelligence. It does not define what intelligence is, or even specify the elements of intelligence. When two dozen prominent theorists were recently asked to define intelligence, they gave two dozen, somewhat different, definitions [2,7]. The problem is much wider than just the field of Artificial Intelligence. The study of the brain and consciousness, with thousands of research papers from the field of psychology and neuroscience, still does not have a single universally accepted definition of consciousness.

As we continue to develop more and more intelligent systems, not having a single universally accepted definition of intelligence will become more problematic for a number of different reasons, not least when we consider the legal and ethics aspects of the systems we build.

We have been asking the wrong question. We should not be trying to find a single definition of artificial intelligence or even just intelligence, but with the understanding that there is a range of intelligent capabilities, we should be looking to define the range of intelligent behaviours. There already is much work in the space to help define theoretical frameworks for intelligence. From the MIT Centre for Brains, Minds and Machines “Understanding intelligence and the brain requires theories at different levels, ranging from the biophysics of single neurons, to algorithms and circuits, to overall computations and behaviour, and to a theory of learning. In the past few decades, advances have been made in multiple areas from multiple perspectives.” [11]

This leads us to potentially complicated frameworks, that leverage the different fields of research to describe them. This becomes somewhat of a impediment to its common use as they are not singularly aligned to the approaches and language used by those using and developing machine intelligence. This article rectifies this, by constructing a detailed but simple definition of the different levels of intelligence on the journey to super intelligence and the singularity. This index of intelligence, or continuum, will have the greatest benefit to describe the different types of artificial intelligence application and systems being designed and built. The index is aimed to help those researching and developing artificial intelligence algorithms, topologies and applications, in describing the capabilities of the technique, and essentially to make it easier to compare methods in terms of their abilities.

Terminology

Some terminology and definitions used throughout this article.

Natural Intelligence

I will not use the term biological intelligence, but rather prefer the term natural intelligence or naturally evolved intelligence to refer to animal and human brains. This is because carbon based science in the form of, for example, genetic engineering and synthetic DNA, is touching on the realms of biological sciences and I wish to make a distinction between this type of engineering from that of natural creation.

Advanced Intelligence

This is the term used to describe artificial intelligence systems that are yet to be designed or built, that progress towards the achievement of super intelligence and beyond.

Collective Intelligence

Demonstrating human level intelligence in multiple domains, as if you had a room full of human experts together having knowledge on different subjects. This level and diversity of knowledge has previously been referred to as a polymath when demonstrated in a single person.

Task

Refers to a challenge requiring intelligent actions related to a specific application and domain.

Application

Refers to the display of intelligent behaviour for a particular task or tasks within a specific domain. For example playing chess. Essentially an application of intelligence.

Domain

Refers to an application area or subject. For example self-driving cars is one domain. Understanding all languages is another domain.

Entity

An intelligent actor (machine intelligence / robot / software agent) or being (human or animal). Natural or Artificial based Intelligence which delivers an intelligence application to a domain.

Model

An internal knowledge representation built up to help solve a given task or tasks.

Before I detail the continuum of intelligence itself, a few topical areas related to parts or all of the levels need to be covered first. A few concepts grouped together under the topic of Information Processing is first, followed by the much more controversial topic of Consciousness.

Information Processing 

Here are some fundamental concepts that I believe are key for our understanding of the advanced development of artificial intelligence.

Data – Information – Knowledge – Wisdom. This represents not only how raw data is turned into useful insights and decisions, but illustrates the layered approach to processing data and information, turning large quantities of data into more refined, compact and useful information. This information is then further processed and potentially combined with other information to create insights and knowledge. This knowledge can then be combined and built up into a store of wisdom. The layered approach and the data volume filtering are key concepts that I wish to highlight here, both are fundamental concept for advance AI.

Substrate-Independent as termed by Max Tegmark, is a fundamental concept. Allowing the underlying methods and approach of the implementation of a computational or information processing task to be independent of the actual computational task. For example, a given sort algorithm does not know or care if it is running on a Windows, Linux or a Mac machine. This argument can be extended to cover the computations and information processing occurring in natural or artificial intelligence, the medium by which the computation occurs does not matter.

Church-Turing thesis is a hypothesis about computational functions. “Philosophers have interpreted the Church–Turing thesis as having implications for the philosophy of mind. B. Jack Copeland states that it’s an open empirical question whether there are actual deterministic physical processes that, in the long run, elude simulation by a Turing machine; furthermore, he states that it is an open empirical question whether any such processes are involved in the working of the human brain.” [22].

There is some work on hypercomputers and super-recursive algorithms that are able to solve so called non-computable functions, however this research is currently not widely accepted. Let us remain optimistic about the workings of the human brain being composed of computable functions.

Consciousness 

This is a very controversial topic. With hugely differing opinions on what consciousness is, and if it is possible to build an artificial intelligence that not only acts consciously but actually is conscious. I want to start this by stating that I completely believe that creating an advanced artificial intelligence that delivers the capabilities outlined by many of the later levels of the continuum detailed below, will have to also deliver a form of consciousness. As with all inventions, initially it would be crude and partial, making it seem as if it is just acting with a conscious but not actually having a conscious, and initially this maybe the case, but over time, I expect the capabilities to improve and deliver full consciousness. I propose, that to deliver the capabilities of advanced intelligence will also, by default, deliver a conscious entity, you can not have one without the other. Some believe that computations alone can not produce consciousness, I believe complex information processing and computations are the essence of consciousness.

“consciousness is a direct consequence of advanced information processing”

History has shown us that whenever we don’t understand something we hold it in very high regard, thinking of it as magical and mysterious, but once we understand, it becomes known and simple. This is common place in many subject areas, and certainly has happened with previous AI techniques and approaches. We are experiencing this with the topic of consciousness at the moment, potentially making it more special or unique than it actually is.

Consciousness, like Artificial Intelligence itself, suffers from not having a single globally accepted definition. The reason for this, is certainly partially to do with the fact, that consciousness covers a multitude of capabilities, from internal thinking, being self aware, having subjective experiences, …

Some would argue that an entity needs to have the capability of language verbalisation in order to have a conscious, and would therefore rule out most of the animal kingdom from being conscious. I assert that this argument is flawed, some mathematicians and physicists have stated that they initial think visually, and only when a new thought is fully formed do they convert it into language. Penrose [23] amongst others, gives arguments and examples to support animal consciousness. Not having a vocal cord seems to be poor reason for excluding the possibility of consciousness in animals.

We also know that when we start to learn a new task or skill, like driving or skiing, we use our cerebrum and focus very hard consciously. But once a skill is learnt, it gradually becomes second nature, requiring us to “think” less about performing the task, as the processing for the task moves into the cerebellum. For me this is key evidence for the layered architecture within the brain, which map to varying levels of consciousness.

I agree with Max Tegmark, who in his book Life 3.0 [21], states that consciousness is substrate independent. For me its not just consciousness, its the entire workings of the brain. The Anthropic Principle [26] in both its weak and strong form, highlights the relationship between consciousness, physics and its place in the universe. The integrated information theory by Giulio [27,28] argues that a conscious system needs a high integration of information processing, and while I agree with elements of this, I believe it is less about high integration and more about Data-Information-Knowledge-Wisdom paradigm that uses information in a layered approach as part of more and more complex processing.

My thesis is that consciousness is a direct consequence of advanced information processing, combined with multiple levels of computational subsystems that deliver a variety of outputs, and is certainly reproducible as a computational simulation. Many of the later levels of the continuum of intelligence cover aspects of capabilities we attribute to consciousness.

Personality & Emotions

Personality can be considered to be the set of habitual behaviours, cognitions and emotional patterns that evolve from biological and environmental factors [15]. As with AI and consciousness, there does not seem to be one widely accepted definition of personality. However, most research and theories on personality seem to agree that its a combination of motivations and cognitive interactions with ones environment.

The Temperament and Character Inventory [17] is an inventory for personality traits, which can give a guide to the range of behaviours that need to be considered to produce an artificial personality. While all personality traits will have an indirect impact on the interactions with other entities, the cooperativeness trait is the most interesting, as this seems to directly deal with interactions with other entities, and the aspects of this trait that I call out for special attention, is that of Empathy and Compassion, as these require an understanding of another entities situation and emotional state.

Exploring in details the complexities of personality is beyond the scope of this article, but I will include more in my book. For now I only need to acknowledge that personality is a collection of cognitive functions, and that creating an artificial entity that exhibits a range of behaviours that would generally be accepted as a display of personality is part of the journey towards advanced intelligence.

The Pardoe Index of Intelligence

We know from looking at animals and humans, that there are obviously different levels of intelligence, but we can also see there are most certainly key characteristics that are exhibited by all sentient beings. It is this fact that should actually help us define intelligence, but acknowledging that there wont be a single definition, that, in one sentence can easily characterise all the aspects that we see in intelligence forms of life.

One of the challenges for creating a definition and thus a measure of intelligence, is that many different aspects of intelligence maybe somewhat independent and developed in parallel.

So, to put some standard measures around the concept of intelligence, I believe the most useful way to to think about this continuum is in the form of levels or an index. Starting from simple displays of intelligence to the ultimate levels of super-intelligence and a technology singularity.

This index will allow the industry to track our progress over the next few decades, showing how we are building more complex and comprehensive technologies, algorithms and platforms that are able to exhibit certain aspects of intelligent behaviour.

It should be noted that while many of these levels are ordered in what might be considered a logical and progressive way, with one naturally following another, it does not follow to be the case for all levels, and as such some might start to be evident in an AI system before other lower levels. This is perfectly acceptable and expected. Also some levels encapsulate very complex capabilities, that may not be possible to fully demonstrate initially, with progress being partial. Again this is totally expected. Some levels are closely aligned, potentially overlapping, others show advancements of earlier levels. This is in part why I have called this a continuum, there is so much entanglement with many of these levels, it truly shows the beauty and complexity of the most amazing object that we know, the human brain.

In my book, I will develop these conceptual levels, allow us to have some quantifiable metrics and score for each AI system. I believe for each index, we would be able to score a particular application from 1 to 10, giving us a total score out of 180. where 0 shows no intelligence and 180 is a fully functioning super-intelligent singularity demonstrating god-like intelligence. For now, I want to focus on the actual index definitions.

P1 – Narrow Single Application Intelligence

A Single Narrow Application, essentially only performs one task. For example language translation from one language to one other, predicting a specific stock price, or providing recommendations for shopping items. There are already many examples of such a capability with artificial intelligence techniques, ranging from rule based decision trees to multi-layer neural networks. We should note that the level of accuracy achieved by any AI application or system, or their inherent biases are not specifically factored into this index, it is expected that the skills of the data scientists and engineers will ensure the optimum achievable performance of the application. Biases in algorithms and datasets are a problem which have a number of strategies to solve, and is outside of the scope of this discussion, as it can be considered a constant issue throughout.  This would be the level of the index covered by the term Weak or Narrow AI

P2 – Single Domain, Multiple Tasks

An application within a single domain. Leverages an internal model or map for that given domain. For example language translation between three or more languages or image recognition for the application of driving. Still Weak or Narrow AI, but more advanced in its approach than the previous level, and more general in its application. The main differentiator between this level and the previous level, is the development of an internal model that maps well to the domain. An interesting example here is the language translation, where it was discovered an internal mapping between the different languages had been formed that surprised the engineers and scientists involved. Development of these internal models are an absolute necessity for advanced intelligence and we should not be afraid of these being developed, even if we are unable to fully understand them.

P3 – Single Domain, Multiple Applications

Capable of applying learnt knowledge across applications within the given domain. So able to play any type of game; board games, arcade games, strategy games, roleplaying games. Or being able to perform self-driving on any type of wheeled vehicle. Maximises the benefits envisioned with transfer learning.

Here the internal model may exhibit what we consider to be strange properties, for example, chatbots speaking a strange language that is not comprehensible to humans. These is an example where the internal model doesn’t easily map to something we would instantly recognise in the real world, but, does not make such a model invalid or incorrect (which has happened with such chatbots being turned off for speaking their own language. For me, this is an obvious thing to happen, we should not be afraid of it happening, but recognise this is a step along the continuum of intelligence development).

P4 – Adaptation

As Stephen Hawking once said, “Intelligence is the ability to adapt to change” [17]. Adaption can come in different forms, from that of continuous learning and seeing new patterns in more recent data, to more dynamic and reactive adaptation that relies on the application of game theory, strategy and tactics.

Strategy and Tactics / Use Game Theories

Ability to negotiate, collaborate and lie to maximise its own chances of success. Demonstrating strategy and tactics. Can work as a team or an individual to maximise benefits. This can be thought of as the first stages of being aware to the point of knowing that there are options to approaching the task, and that there are multiple actors in play.

Online and Offline Learning

Ability to learn from its mistakes and learn new things is also part of adaption. The offline learning might be considered, from a nature perspective, encapsulated in the act of dreaming (or maybe dreaming is the consequence of offline learning/training). This can come in the format of feedback from external sources, or more gradual changes from the training data, as the system is frequently re-trained to ensure it picks up this drift in the data.

P5 – Aware of its Environment (Local and Global)

Self-aware of its environment. Understanding the environment and how that effects its own tasks. Demonstrating consciousness at some degree of completeness.

This is going to be a particularly controversial level, as I know there is alot of discussion in the literature about this topic. Arguing if consciousness is even possible with artificial intelligence regardless of the implementation method. Rather than get into deep arguments about this, I will simply state that one of the problems with many of the arguments is the lack of definition of what they mean by consciousness. And without that it is simply pointless having a discussion. So lets start with that. And in actual fact I have broken the definition of consciousness into several parts, with higher order of consciousness being covered in levels P6 – P12. The awareness elements of consciousness are covered in this level. By aware I simply mean having some map of the environment. And with everything in this article there are different levels or degrees of awareness that we must recognise.

Deep Blue and Alpha Go algorithms where aware of the virtual boards on which they were operating on, but did not understand that the game was actually being played in the physical world, in a room, with an audience, in a building, in a town or city, in a country, on planet earth, within the milky way galaxy, etc. But then one could argue it didn’t need to know all of this. It might be useful to know it was playing a real game, against a real person, against the world champion in actual fact. But is it important it knows what city it is situated, would that alter the way it would play the game? Maybe, maybe not. The point is there is multitude of different scope and size when we look at the environment in which an entity is self aware of.

Also we should note, that our intellectual understanding of an environment can change as we learn more. As humans, many years ago, the leading theory on our world environment was that the world was flat. We now know this to completely incorrect, but what this means is our model of the environment changed. We were still as self-aware as before, but our view on the environment has changed.

Anyway, getting back on topic, I believe that an intelligence that can demonstrate an understanding of its immediate environment is an important step towards full intelligence.

I also believe that once you have an intelligence that is truly self-aware, it will want to expand its map of the environment.

Being aware of an environment is only part of the puzzle of this level. It must understand how the environment might change factors that effect the task it is performing, allowing it to continue to adapt its approach based on changing environmental conditions and factors.

P6 – Self Aware

Self Aware is a natural progression from being aware of the environment in which the entity is within. Understanding one’s own place within that environment, Understanding who and what you are and how you can affect the environment which you in, are key factors to being self aware. As with all of these levels, there are varying degrees of achievement here relating to different aspects of self awareness.

One of the most amazing things to see in nature is when a kitten first sees itself in a mirror. There is a period of time when it does not recognise what it sees in the mirror as itself, and starts to perform a dance to scare off the stranger. Eventually the kitten learns that the reflection is indeed a representation of itself and then starts to ignore the image (or atleast isn’t threatened by it anymore).

To recognise oneself is the first stage, but to then to be able to correctly categorise oneself and recognise similar entities is the next stage of being self aware.

We can see in the development of baby humans, that their awareness of the environment, and awareness of themselves within that environment develops over time as their cognitive capability advanced in their first few years of growth. But we would also argue that the baby is conscious from birth, despite having very limited awareness.

P7 – Explain its Reasoning

To be able to explain its internal thinking or model (models) and to be able to reason and have a rationale for decision making. This is another key element of demonstrable consciousness.

Those developing these advance AI systems, actually want to understand how they are working and will no doubt continue to do so, and thus will naturally want to build the mechanisms that allow the rationale for decision making to be exposed.

But we must acknowledge that even humans are not always able to do this, using the term instinct or gut feeling to explain some thought making processes. This might be because some of the decision making process happens with our unconscious mind, making it more obscure to define. And maybe there is good reason for this that we don’t understand. Maybe some decisions are not fully defined by a logical reasoning, and the emotional aspects of decision making are more difficult to describe.

While we seem to accept this in humans I believe it will be sometimes difficult to accept the same argument from our machine intelligence entities.

P8 – Cognitive Independence

To combine multiple communication methods (language / mathematics / music) and to demonstrate full human like cognition functions across the senses, motor skills (physical motion), emotions.

As with any system, input and output are key elements, without which it would be very difficult to fully function. Taking those inputs and outputs from simple binary representations of information, to be fully integrated with the physical world is going to be significant step in the evolution of artificial intelligence. This field is developing well with the various robotics initiatives currently in flight.

Enabling AI to build its own internal models for the various methods of communication is hugely important and we will no doubt see communications that interface with humans but also communication methods that only other AI can understand. There is an ethical issue here that no one has even thought of before (we have seen examples of chatbots speaking with each other in their own language, and the way we have dealt with this was to simply turn them off. This is not a sustainable approach, and actually demonstrates how scared we are of our own progress).

I would like to separate the development of advanced intelligence from that of mobility in the form of robotics and androids, however, it will be a significant step for humans to accept advanced intelligence by experiencing it in a familiar form, so the field of robotics will be an important technology running alongside that of AI. While we will experience all forms of robotics, and it is unclear at the moment if human like androids will be widely accepted, it is a current field of research. However, I am reminded of a recent experiment in which two teams of humans augmented with a robot helper had to work on a team task. The team with the robot that made mistakes was considered more of a team-mate by the humans than the robot that performed perfectly. I guess no one likes a know-it-all.

The field of robotics is developing strongly by working in partnership with AI advances. Learning to walk, run, jump, recognise objects, use its robotic hands to pick up a multitude of different shaped objects just via trail and error, and even catch balls thrown towards it. We must remember that it isn’t the robot that is smart, after all, its just a mechanical machine, its the AI brain that controls it that provides the human like capabilities.

P9 – Personality, Emotions, Empathy & Compassion

Giving our artificial intelligence applications a personality will make them individual and unique. But do we want our AI systems to define their own personalities, or have them pre-defined or pre-programmed. Do we want our personal assistant to be moody or angry?

Going into the complexities of personality for the purposes of this article is not going to be possible. However we acknowledge that being able to simulate personality in a way that provides unique and individual personality without developing extreme behaviours will help with social engagement and acceptance of advanced AI agents.

Personality is a reaction to a defined set of emotions. Different people can see the same image or video and it will make them react in different ways and at different scales. No doubt this is a combination of our current emotional state combined with a defined emotional reaction to input based on past experiences. A complicated mix that ultimately will define a response that is then perceived as a personality or emotional response.

One may ask why do we need such capabilities in our AI systems. And for many we probably don’t. But for robots / androids that are regularly interacting with humans, having a personality that can make it easier to interact with humans is going to help with the integration between the two forms of intelligence.

To show empathy and to understand other entities situation in the given environment. To know right from wrong. Able to form relationships and interactions with other entities. To demonstrate emotions. All of these are going to be hugely important as we see more and more AI applications, agents, systems and robots enter our personal and professional lives. We will need such AI to be able to empathise with us, to adjust its approach towards us based on the specifics of our situation.

P10 – Self Governing

To show empathy and to understand other entities situation in the given environment. To show compassion for another entities situation. To know right from wrong. Able to form relationships and interactions with other entities. To demonstrate emotions. This is rolled up into the demonstration of personality, however, how the entity reacts to situations, needs to be regulated. In human behaviour, we sometimes refer to it as ‘common sense’.

Here we demonstrate higher order consciousness by exhibiting a social and moral compass. To understand cause and effect.

Without getting into the details of how this type of intelligent capability might be implemented. This is where we might think of the laws of robotics that Asimov defined, and opens the debate as to how these “rules” of self governing should be encoded. Should some of them be hard-coded, never to be changed or removed, while others can be added over time. One might argue that humans know right from wrong, and usually follow these from a morale and social perspective, but these are either not hard-coded or can be overridden depending on the circumstance, situation and/or the decisions made by the individual. Do we allow our AI and robots the same potentially deadly capability to decide when to follow the rules or not?

P11 – Self Learning

To understand the current limits of its own model / thinking and be able to expand its knowledge which in turn improves it’s models. We currently have systems that use online or near-line training to adapt to changes in the underlying data and ensure the model is performant. We are also starting to look at modifying the topology of the network of neurons before and during training.

A human brain adds around 1,000 neurons each day, allow us to continue to learn new things, save new memories, alter our thinking or repair/replace bad neurons. We have only just scratched the surface in this particular area, but there is lots of interesting advancements already.

This will be a major capability required to achieve a technological singularity, but here we are only talking about adaption and evolution that is controlled and constrained by our own human understanding.

Being able to extend existing models, making them more complex or even simplifying them depending on the circumstances, is an essential part of continued learning, being able to essentially replace one model with another more accurate version, is key to self learning capability.

P12 – Self Doubt / Challenge its Models / Belief System

To have an element of inbuilt doubt that acknowledges that the application may not be in command of all of the facts that apply to the given situation. This is what Stuart Russell refers to, and suggests we need to factor into AI in order to safe guard the human race from potential extinction events caused from an AI thinking it is doing the right thing, but not understanding the bigger picture, or have all the facts at its disposal.

Includes potential for spiritualism and religious beliefs, which itself opens up a huge topic of discussion as will an artificial intelligence of human like capabilities see humankind as its god or develop beliefs aligned to human religions. Or does the development of advanced intelligence not need the support of a belief system.

There has already been the establishment of the first AI religious group called the Way of the Future who’s purpose is to develop and promote the realisation of a Godhead based on artificial intelligence [12], will advance AI worship an AI based god?

This is a hugely fascinating area that until now has not really be discussed that much, but I would suggest that as we develop more complex AI, this area of study will increase as the need to support such capability increases.

P13 – Internal Self-Modifying / Evolving / Self-Design

We already have methods that modify the topology of the neural network, pruning neurons for example. Taking this further, we will construct AI systems, that design optimum architectures and learning algorithms that maximise the capabilities of AI applications.

This self-design will form the foundations required for the singularity, but at this level will be simple methods and approaches, and will be unlikely to involve dramatic changes or complete re-design.

This level of development might be considered a horizontal level, that is incrementally improved as we advance across the other levels. It will be matured as we head towards level P17 – The Singularity.

Where natural intelligence uses the DNA genetic mechanisms of mutation and crossover to gradually evolve new capabilities and functions, our advanced intelligence will apply a much faster method of evolution of self-design. The ultimate progression of the self-modifying or self-design capability will only be evident in the singularity level, but will be the most powerful form of evolution that we will ever encounter.

P14 – Single Domain of Expertise / Human Intelligence

For a single field of expertise, with significantly broad and deep knowledge, being able to better a human being is a major milestone. How we measure this is going to be very important. As an example, there is a lot of focus on building self driving vehicles at the moment, and while we are able to train a system that has technically more driving miles “experience” that any human could acquire, we don’t have a single entity that can fully drive any car, lorry, motorbike, etc. So while we are making amazing progress, we are still a very long way from achieving a close to human capability with driving. And here we should make the distinction that we should set the bar high, and it should be an expert human in comparison, so in this example, a single human that is able to drive all types of vehicle, from the largest truck or lorry to the smallest of motorbike.

P15 – Many Domains of Expertise / Collective Intelligence

While we have a few examples of humans being experts in multiple fields, referred to as polymath, this is the exception not the rule, and as the universe of our known knowledge is increasing at a tremendous rate, it is becoming more difficult for a single human to achieve polymath status. Hence the term Collective Intelligence, referring to the intellect of a room full of human experts of different fields of knowledge.

Able to combine expertise across several related domains and having those domain models seamlessly integrate giving rise to true collective intelligence.

This will be a wonderful milestone for humans, as we will have systems that can provide amazing insight into subjects, that might take humans much longer to develop. Help us to create new medicines to cure illnesses, create new molecules and materials, design new products, deliver new services and produce new art. All of this and much more will be possible. And actually we have seen repeatedly that good things happen when we cross subject borders and bring expertise from two areas together or take discoveries from one area and apply them into another.

P16 – All Domains of Expertise / Partial Singularity 

Able to combine expertise across a multitude of disparate domains and having those domain models seamlessly integrate giving rise to true singularity.

At this stage we get to the point that the AI is able to understand the fields of technology and artificial intelligence, enabling it to modify itself, but much more than will be achieved in level 11. Level 11 is only going to be focused on limited improvements. Here the changes will be driven by truly understand the subject matter, what has been currently achieved and what is possible.

The singularity will not only deliver rapid technology change, some of which will enable it to improve itself, but it will make advancements in all topics and subjects it understands. The rate of change and advancement will be, to humans, astonishing, and we will truly struggle to keep up with understanding what is being suggested. Potentially we will have to accept changes that we just don’t comprehend. This will be a significant milestone in human development, and no doubt will not come easy. As for centuries we have been comfortable in the position of most intelligent entity in the world. To give this position up, and trust in the machines that we have built will be a huge leap of faith.

P17 – Singularity / SuperIntelligence

Part of the Singularity is the ability for continuous improvement, self-modification and redesign to facilitate improved performance and abilities.

Natural intelligence in the form of the brain has evolved over millions of years, and currently takes a number of different forms, with wide ranging brain size and number of neurons across different species within the animal kingdom. Evolution with technology has the potential to occur much faster, with “new versions” of both the hardware and software able to happen exponentially quicker than with natural evolution. Being able to design itself, creating improved versions of itself in one generation, is immensely powerful, and has the potentially to completely run away from our own understanding. For me one of the most interesting questions here will be what medium the entity chooses to built itself, will it stay a silicon based entity, will it migrate back to carbon, use a hybrid approach, or selection another technology as yet unknown.

Another element of the singularity or super-intelligence is that of making dramatic inferences and advancing knowledge beyond what we would consider to be a normal or even exponential rate of advancement.

A final aspect of this level, will be our own incomprehension in both its findings and its fundamental understanding.

P18 – God like Intelligence

Taking the super intelligence further, it will develop so fast and so complex, that it will supersede our own cognitive understanding, both of how it is working internally and its understanding.

“When the intelligence becomes so advance, that we, as mere humans, are completely unable to understand it; we will see it as totally mysterious and magical.”

We will see the things that it does as miracles, as master of everything it does. We are most likely to hold this entity in the same light as a God.

While many people will find this idea most disturbing, even blasphemous, this is I believe, the last level of the continuum of intelligence. At this point, the entity will be all seeing and all knowing, and will have achieved the most extreme level of advanced intelligence.

And just maybe this is when the universe will start another cycle of creation.

Summary and Conclusions

Until now, we haven’t had a way to properly measure the progression of our efforts towards advanced intelligence. The Turing test gave us a way to measure a very specific milestone along the continuum of intelligence, but fails to give us a way to track our progress either before or afterwards. The Pardoe Index, in its current form (as given here) is very high-level and coarsely defined. The index while ordered in some logical progression, it is acknowledged that developments will happen across the index at certain degrees of completeness. I plan to expand in much more detail on each index level, and give a finer grained definition of each level, that will allow us to determine if a particular AI system is fully compliant with any given index level, watch out for my book of the same title to be published in 2018.

The true purpose of life and the universe, is the advancement of intelligence.

The journey to advanced intelligence, during this golden age of the algorithm, is going to be one of the most exciting periods of human history, with huge positive potential if we get it right. Let us all hope that we demonstrate our own intelligence to consider all aspects of advance intelligence entities (before we switch them on) and that they show us more respect and compassion than we have shown other entities of lower cognitive abilities in the past.

If we do not embrace and integrate with the technology driven advanced intelligences of the future, we seriously risk becoming as extinct as the Dodo.

Appendix

Related Topics

During the research and writing of this, a few topics have manifest themselves which while I have not include in the main index, require some mention.

Dreaming

What is the true purpose of dreaming? Most if not all natural intelligent entities appear to need to sleep. [while many animals exhibit sleep with the whole brain entering a sleep cycle, some dolphins for example are able to “shut down” half of its brain into a sleep mode, while the other half of the brain remains active as normal]. No doubt part of this is to rest and repair the body. Is dreaming purely the result of the brain having limited stimulus from its normal inputs (senses and nervous system), or is it an important cognitive process that all natural intelligence entities have?

One must also consider that nature of dreams and the action of the mind to add neurons and build connections during this “offline” period. One might equate this to batch based learning, verses online or near-line learning that we are familiar with as data scientists. I am keen to identify all the aspects that will be required for true intelligence. Consciousness is one obvious aspect that is required, maybe the second required aspect of intelligence is that of dreaming (offline learning).

Simulated Behaviour verses Actual Behaviour

For a computer scientist, this is an interesting topic. When does a simulation of something actually become the real thing. For humans, we know when we are faking an emotion, compared to the real thing. The difference between acting and reality. To quote shakespeare, “the world is our stage”. So when does simulating an action, behaviour, or emotion become real? I believe the answer is simply  when its complete and feels real. The substraint-independence rule applies here too. We don’t need a biological eye to see, and we don’t need a biological brain to make decisions or run calculations.

Carbon-Silicon Hybrid Intelligence Augmentation

One way in which humans may avoid extinction to advanced artificial intelligence, is to become integrated with it, a form of cyborg, combining the best of nature and technology together. This is a view shared by many leading AI researchers as one approach to avoiding being superseded by AI and potentially also avoiding the potential threat of being exterminated by super-intelligence AI as the human’s will, with this hybrid augmentation, retain control over the advance intelligence. [13]

A Diversity of Experts

It seems that the topic of the intelligence and the mind brings together experts from many different fields, including neuroscientists, physicists, mathematician, phycologists, philosophers, computer scientists, linguists, biologists, and no doubt many others. I have been particularly intrigued with the works of many physics and maths experts on the topic of intelligence. The emergent phenomena from physics seems to warrant them with the ability to claim ownership of any discovery, as it all boils down to particles and energy. I am reminded of an episode of the Big Bang Theory where Sheldon and Amy are arguing about this very topic, and Amy reminds Sheldon that all physics theories are created by the human brain and therefore the domain and creation of neuroscientists. I wish to follow a similar argument and conclude that the best commentators of information processing and computation, regardless of its form, should be from computer scientists.

Darwin and the Survival of the Smartest

Darwin was wrong, atleast partially. While survival of the fitness works with low cognitive capability species, as the dominant factor then becomes “fit” to the environment. With an abundant environment many species survive, with a changing environment or one with scarcity, some win and others lose, but its as much luck as judgement. The true survivors and ultimate winners, are those who adapt to changing environments quickly, those that exhibit intelligent behaviours. And so its the “survival of the smartest”. Once can argue that “fit’, on average, could mean those best able to adapt, but I think Darwin’s interpretation of fit is actually more about alignment to the environment conditions than immediate adaptation.

The Golden Age of Algorithms #GoldenAgeAI

The Golden Age of Algorithms #GoldenAgeAI

It seems obvious that the future of wealth and prosperity will be driven by expertise with advanced algorithms. Some call it the next Space Race, others the next Arms Race, either way, we are entering the golden age of the algorithm. This is not only a national race, but also a commercial and individual race too. And calling this an Arms Race or Digital Warfare is probably more accurate than a Space Race.

We have already heard about an AI fighter pilot that is more performant and capable than the best of the best human test pilots, and AI applications are helping to defend against security cyber attacks. Computers are hacking computers. How is this not digital warfare?

But this isn’t just about traditional warfare, this is about business and commercial success too. Only those companies that embrace the benefits that advance algorithms can deliver will survive. This will be the new major differentiator for firms. One only has to look at some of the trailblazing firms to already see this happening. Business models are changing, dramatically, with global startups, unicorns, having defined the landscape of many traditional businesses.

Algorithms will have a massive impact on individuals too. In many cases they already are, from mortgage approvals, medical diagnosis, recommendations for purchases, to who you should date, they touch our lives in so many different and usually hidden ways that one can argue we are already being shaped and controlled by the power of the algorithm. We do this as we trust that data holds the universal truth and that we are making better decisions by putting our faith in the algorithms that analyse these huge datasets.

This raises alot of questions around AI Ethics, AI Governance and AI Safety, these are hot topics that many high profile advocate is highlighting a need for more investment and research on these subjects to support the rise of AI in general. Without these support frameworks the algorithms could spin out of control.

Are you ready for the golden age of algorithms?

Dr Andrew Pardoe – Written evidence (AIC0020)

What are the implications of artificial intelligence?

Introduction

Dr Andy Pardoe has a doctorate in artificial intelligence and is the founder of Informed.AI, a community of websites for AI supporting those interested to learn more or working in the industry. Listed by IBM Watson in the Top 20 of Global AI Influencers, listed just below Elon Musk. He runs the annual global achievement awards for Artificial Intelligence. A member of the British Computer Society Special Group for Artificial Intelligence committee. Currently work for Credit Suisse designing their own Machine Learning Platforms and Applications. Andy is an International Speaker on Artificial Intelligence, Machine Learning and Robotic Automation.

These are my own personal views.

Questions to be address

  1. The current state of artificial intelligence.
  2. The pace of technological change and the development of artificial intelligence
  3. The impact of artificial intelligence on society
  4. The public perception of artificial intelligence
  5. The sectors most, and least likely, to benefit from artificial intelligence
  6. The data-based monopolies of some large corporations
  7. The ethical implications of artificial intelligence
  8. The role of the Government and
  9. The work of other countries or international organisations.

The current state of artificial intelligence.

While the field of AI has been around since the 1950s, it is only in the last 5 to 10 years that a number of factors have come together to establish an unstoppable progression towards super intelligence and the singularity. Those factors being, (1) the advent of large qualities of data facilitated by big data technologies like Hadoop and Big Table, (2) via Cloud platforms access to scalable computing infrastructure, (3) via the gaming industry multi-processor technologies in the form of graphical processing units (GPUs) and lastly (4) advanced learning algorithms and topologies that enable deep learning neural networks and reinforcement learning. Currently most applications of AI are what is call Narrow or Specific AI (meaning a very targeted application) which a number of companies and research institutions are working on AGI (artificial general intelligence) which holds the promise of delivering super intelligence. However, most knowledgeable commentators believe that AGI and Super Intelligence will not happen for another 20-40 years.

The pace of technological change and the development of artificial intelligence

As detailed by the World Economic Forum, we are at the start of the fourth industrial revolution, and what is most evident is that the rate of change for technology development is increasing at an exponential rate, and we are at the inflection point, where we will see in the next 10-15 years the same amount of change as we have seen in the last hundred years. It is clear to see that the next 25-50 years will be an amazing time of change and transformation. The level of complexity and intelligence shown by our machines will be astonishing and that of science fiction for many. With so many different technologies (Robotics, 3D printing, crypto-currencies and block chain, Virtual and Augmented Reality) becoming mainstream and being integrated together the possibilities are endless for the enabling technology of AI.

The impact of artificial intelligence on society

As with any industrial revolution the impact on society is immense, and will be perceived as both positive and negative, The challenge with the fourth industrial revolution is that its potential to impact every single profession and industry, large and small. Even those industries that currently appear to have a low dependency on technology are also in scope for impact. Both low and high skilled professions will suffer from job displacement, and the need for a universal basic income is real. Highly skilled professionals will learn their trade from AI agents in the future, as the normal method to learn wont be available as AI agents will be performing the basic functions that were previously used to learn the trade. Every role will be augmented to some degree by AI agents. In the near future entire companies could be fully automated, with only a handful of human staff who own the company, and deal with operational changes needed, with all other tasks being managed by computer and robotics. Another aspect impacting society will be the social interactions of intelligent robots and androids with humans, and more specifically how humans will consider and react to andriods.

The public perception of artificial intelligence

As detailed by the Royal Society Report on AI that surveyed the public, many do not know the specific details of AI. but most understand the applications of AI, including self-driving cars and personal assistants on mobile phones. Overall the perception of AI has been positive with the general public, but there is a high risk of misunderstanding of its abilities and capabilities due to the complexity of the techniques and the fact that the field is still relatively new and frequently improving. The concerns around how we manage AI ethics, safety and legislation together with areas like autonomous weapons put at significant risk the positive perception of AI with the public.

The sectors most, and least likely, to benefit from artificial intelligence

All sectors will benefit from AI, just some will benefit sooner than others. The sectors that will be slower to benefit from AI will be those that are highly manual and / or creative in nature. Will we want to watch a theatre production of Shakespeare’s Hamlet performed by robots. One of the unseen beneficiaries of AI are Charities, as advance data analytics can help a charity better target its services to those in most need, companies like DataKind are facilitating such activities.

The data-based monopolies of some large corporations

While this is a concern, this is already happening without the advent of Artificial Intelligence. From an AI perspective, what we really should be concerned about is that the super intelligence and singularities ALGORITHMS and MODELS are not owned and controlled by a few large non-UK corporations. We need to make sure the UK has a seat at this table and our own talent do not all work for foreign entities. More seed and growth investments for UK AI entrepreneurs is needed. Fundamentally the Algorithms and Models are the engine of machine intelligence, Data is just the fuel.

The ethical implications of artificial intelligence

The transparency of decision making seems to be of importance for the acceptance and adoption of AI in many areas, despite this not being the case for the equivalent human decision makers. This transparency not only relates to being able to audit the internals of the neural network in terms of the features it is using to make a decision, but also to have visibility of the data used to train the system, so that any biases can be seen, or rather it can be demonstrated that any intrinsic biases in the data have been removed or compensated for during the training process. There are other ethical concerns with AI, especially where there is not an obvious right and wrong answer and either outcome has consequences. How can we impose the ethical and moral standards of the user of the AI system rather than rely on the default programmed into the system and thus encapsulating the ethical standards of the coder or the underlying training data.

The role of the Government

There are a number of areas the government can support the adoption of AI and position the UK as the leading authority on AI. Firstly, ensure a strong pipeline of students from school with strong computer science teaching, to university with more courses at undergraduate level and more secondary degree options. Secondly halting the brain drain of researchers and entrepreneur working for US or other non-UK companies. Thirdly, better support for entrepreneurs with seed and growth capital to stop startups being bought by non-UK large corporations. Fourthly, supporting initiatives like Informed.AI who are focused on knowledge sharing and education to ensure a positive perception of AI continues. Fifthly, being ready to support the universal basic salary when AI job displacement reaches levels that require the government to support the general public. Finally, embracing any minor legal changes needed to facilitate the rapid adoption of AI systems.

The work of other countries or international organisations.

Given my Informed.AI platform, that has users from all over the world, I get to see activity from every country. While there are the three obviously epi-centers of activity for AI, namely America, UK & China, there is one other emergent country that is noteworthy, and that is India. A hub of outsourcing IT at the moment, many of India’s leading vendors are building out there AI platforms and capabilities. Informed.AI is an international organisation, with a global team and a number of global initiatives including the meet up chapters of Neurons.AI and the Global Achievement Awards for AI.

A response to the Science and Technology Committee inquiry into robotics and artificial intelligence

The potential of robotics and automation and the related technologies, namely artificial intelligence and machine learning, supporting the development of these capabilities are significant and it is very encouraging that the government have requested expert opinion about both the impact and opportunities these technologies offer. Acknowledgement must be given to the Robotics and Autonomous Systems (RAS) Special Interest Group, the strategy it published in 2014 and the governments response published in March 2015. The response states actions taken for each of the eight recommendations.

The Science and Technology Committee requested submissions covering the following four areas;

  • The implications of robotics and artificial intelligence on the future UK workforce and job market, and the Government’s preparation for the shift in the UK skills base and training that this may require.
  • The extent to which social and economic opportunities provided by emerging autonomous systems and artificial intelligence technologies are being exploited to deliver benefits to the UK.
  • The extent to which the funding, research and innovation landscape facilitates the UK maintaining a position at the forefront of these technologies, and what measures the Government should take to assist further in these areas.
  • The social, legal and ethical issues raised by developments in robotics and artificial intelligence technologies, and how they should be addressed.

1. The implications for the future UK workforce and job market

One only has to look at the enabling technologies that are developing that impact the taxi business. The first technology was satellite navigation (satnav) which has enabled everyone to have the “knowledge”, the second is the scheduling and booking software, think Uber, which has brought convenience to the process of getting a taxi to the consumer. The third transformational technology is obviously the self-driving cars. Combining all these technologies together, and you have an industry that is completely transformed with the potential to remove the need for taxi drivers from the picture. With this we need to consider where a human driver could add value in the process, for some types of journeys, a chauffeur adds value and prestige. Sometime people need help with there luggage and directions when they arrive at destination. So we need to consider that these technologies are not fully automating the process, but augmenting the process, freeing the driver to focus on more important customer service and value add services.

This is a really important aspect of the transformation that robotics and automation will have on the labour force. In many cases, RAS does not have to fully remove humans from the picture, we embrace the ability for RAS to remove the monotonous tasks from a given job. This is what I refer to as augmentation [1, 2]. Augmentation has the ability for RAS to support the human labour force, allowing the humans to focus on more complex or value add tasks.

We need to educate the population not to fear the advent of technology transformation on the workforce, but to embrace the freedom that it brings. RAS delivers augmentation, which removes the dull repetitive tasks from the job and frees the human to focus on the more interesting, value add, complex tasks.

Given this, many industries will need the workforce to be trained to embrace the changes that RAS technologies will deliver, and understand the changes to the work, focusing more on more complex or value-add tasks.

The other aspect to the workforce and job market, is the need to educate people on how to empower RAS. We need many more people to have a solid understanding of coding. Computer programming is the new language for the 21st century, and we need everyone in the UK to be able to speak it. Coding is important but providing the ability to think in system terms, integrating separate RAS systems to deliver a combined solution will be increasingly important for us all in the near future. There is work done by many companies and initiatives to help educate the workforce, including decoded.com and homeAI.info. These initiatives should be supported more via government grants.

We need to start as early as possible with this skills training. Children are the most receptive to technology and seem to have a natural instinct to adopt them. We should make computer science a foundational subject as much as english and maths is. After all, technology is our future, and those that don’t understand it, and can use it, will get left behind.

It is encouraging that the government via is RAS Challenges is positioning the UK as one of the best places to develop self-drive vehicles, but developing this technology is only part of the story in terms of enabling its adoption, workforce strategy, legal and ethical implications and social factors need to be considered and should be provided for.

While I have used the self-driving cars as an example, it is obvious that the same concerns and factors would be found across many other real applications of RAS.

2. social and economic opportunities exploited to deliver benefits to the UK

The development and commercialisation of RAS technologies has the ability to delight, enthuse and empower a nation. This effect, to be leading the next industrial revolution, should not be understated from both a social and economic perspective.

However, we will need to help the nation make the journey from mystique caused by limited understanding of the technologies to acceptance via information and knowledge of how these systems work. Training and education is a key to the social acceptance of such technologies not just to the ability to create and develop such technologies. If as a nation we can rapidly accept RAS, and accept the changes that augmentation will bring to our lives, we will free ourselves to deliver more economic value to the UK but focusing on more complex and worthwhile endeavours.

With people working less risky and manually intensive jobs (as these will be augmented by robotics and automation), combined with the development of life prolonging methods (medicines, food, age reducing), the population will grow quicker than currently expected and we will have more opportunities for recreational activities to be more frequently available to people. We will have a more utopia outlook, with people working less, living longer and focusing on developing their skills and interests for pure recreational purposes.

3. funding, research and innovation landscape facilitates the UK maintaining a lead position

If the UK wishes to be at the forefront of RAS, then we need to give startups much more support than we currently do. I personally find it frustrating that so many good machine learning startups are being funding or outright purchased by US controlling companies. We need to stop this. Why cant the UK nurture more of its own leaders in this sector. There is no point us having the raw talent and skills needed to provide leading companies in this area, if we then give them up easily to be rolled into the US economy. We should make it a lot easier for startups and developing companies to gain access to funds to continue its research and development activities without the immediate pressures of producing commercial products immediately. We need to support our talent to produce world leading enterprises. The evidence seems that at the moment we are not supporting these companies enough.

While we see that the work Innovate UK and Research Councils, as acknowledged on the commentary on recommendation 2, is bringing together the research and innovation communities by fostering various relationships, there still seems to be a gap from academic activities to commercial enterprise. However, as mentioned with recommendation 5, the cross sector grand challenges, appear to be a perfect platform to develop complex applications of RAS technologies and will help bring the various communities together.

4. the social, legal and ethical issues raised by such technologies

With such a transformational environment, the impact on social, legal and ethical issues are non-trivial. There should be a body established (as there has been in the US) to look at how the technology industry can be supported by considering these aspects. In fact in the US, there have been a number of institutes setup that are concerned with such issues, I am not sure if this fragmentation is helpful. I also believe that there is a real risk of over hyping the social and ethical concerns with such transformation. From the industrial age onwards, we have seen many new technologies introduced into many different sectors, while there may have been some initial resistance, it is difficult to halt the adoption and progress of such. We need to provide the support and guidance that will allow such adoption to be done in a gentle and positive way.

There will no doubt be situations where legal and ethical concerns will need to be addressed, if we don’t act now to start preparations on the legal system to allow the freedom of adoption, the UK will end up being behind other nations. We should continue to have the best legal system in the world that acknowledges and copes for such technology advances. Ethics is an area that has far reaching implications, from the development of the systems, to how they operate, to the bias of any legal system that oversees the implementation of an ethical framework. I would suggest that an ethical framework will be the most difficult aspect, and we have to remember that we don’t have such a framework now, and we instead rely on manufacturers of machines and systems to do the right thing and leverage the legal system to deal with breaches of such trust. So do we really need an ethics framework if the legal system is updated to consider these new technologies.

The social aspects are complex, and span both the changes to the workforce environment to the empowerment that such technologies can give individuals. It will be seen that RAS deliver huge benefits but can, in the wrong hands, deliver devastating results. It must be knowledge that any machine or technology can use applied for good or bad. You only have to think about nuclear fusion for an example of this with the atomic bomb and atomic power stations. Its less about the technology itself but how we decide to apply it. Maybe this leads to a way to licence such technologies for appropriate use, by appropriate bodies, but this may then just force the development of such technologies underground, which would properly be more harmful in the longer term. As part of this we have to ask ourselves now about the implications of autonomous weapons, and who is responsible if such incorrectly targets friends.

summary

In summary, the area of machine learning, robotics and autonomous systems will no-doubt be known as the next industrial revolution, and the UK must be front and centre of this transformation. Establishing a RAS Leadership Council to provide the independent advisory and oversight to deliver the RAS strategy will become increasingly important over the next three to five years.

There are many aspects to consider over and above just facilitating the skills and talent to develop such technologies, we need to be able to navigate the complex ecosystem of research and innovation to empower the transition to the marketplace. We need to support startups and companies so they can remain to deliver economic benefit to the UK rather than see them be transferred to other countries.

Initiatives that look to train people in coding should be supported more via government grants.We should make computer science a foundational subject as much as english and maths is. Training and education is a key to the social acceptance of such technologies

There should be a body established to look at how the technology industry can be supported by considering the social, legal and ethical aspects. We should continue to have the best legal system in the world that acknowledges and copes for such technology advances.

Robotics and Autonomous systems have the potential to deliver huge advantages and benefits to the UK if we are able to accelerate the adoption and leverage the augmentation of such technologies.

The Four A’s Pyramid Framework (Part 2)

The Four A’s Pyramid Framework for Artificial Intelligence and Machine Learning (Part 2)

Defining Augmentation – Making the Leap From Analytics to Augmentation

 

Following on from the previous introduction article on the Four ‘A’s Pyramid Framework, we need to determine how we will make the leap from simple analytics to augmentation.

The combination of big data technologies with highly parallel computing power has enabled huge advances is data science, analytics and machine learning. Particularly giving us the ability to better visualise and understand the data being analysed.

Leveraging these advanced analytics including clustering and predictive algorithms on the surface appears to be very easy. There are many platforms now that make the task of training and deploying a predictive model relatively easy. However, while this maybe initially true, this simple setup doesn’t consider a number of important factors that will deliver robust and resilient intelligent systems longer term.

FourAsAugmentation

Lets consider the definition of Augmentation.

Augmentation is about providing the capability to support human activity via computational methods.

This maybe by providing visualisation of information and insight though clustering or ultimately via regression and classification to predict the correct outcome for a given application. Augmentation has the ability to take on the simple tasks previously done by a human, freeing the human to perform the more interesting or complex tasks. There are wider social and workforce implications with this, but they will be covered in other articles. For this article we will focus on the technical aspects.

There are gaps between the platforms and frameworks that are currently available and what is actually needed to provide smart, robust and resilient systems for augmentation.

So what is missing?

Well what we need to understand is that training a predictive model is not a one off task and the data will inevitably change over time and will vary to what the model was trained on. This essentially has the effect of reducing the performance (accuracy) of the model over time. One approach to solve this is obviously to continually train the model, which does make sense and has the potential to deal with varying data over time (active learning). But this itself brings its own set of challenges. Including how do we select the right sample of data to use to train the model. How do we prevent localised skews or abnormalities in the data. How do we ensure that infrequent events are represented and can be part of the generalised model.

In addition we must factor in confidence levels from the model to determine if a specific prediction should be fully automated or needs to be reviewed by the user. The specifics of this will of course vary from application to application, but a standard way to perform this would be useful.

Also another key area that appears to be missing from the current platforms and frameworks is a standard way to feedback from the human as part of this close interplay between the user and the automation that underpins the augmentation. When the human flags a mis-classification, how does the machine learning model factor this into the re-training of the model.

Producing a system that can make accurate predictions only takes us part of the way to delivering a system that can augment tasks successfully over the long term. Any machine learning platform will need to provide algorithms and solutions to the above identified gaps before we can produce robust and resilient intelligent system.

What needs to happen next is to deliver platforms that can augment manual workflow by providing semi-automated systems that support business process and enable the subject matter experts to focus on the more involved and complex elements of the business

While there is a lot of excitement and optimism of what we can achieve with machine learning algorithms and techniques, we need the platforms and integration layers to facilitate a number of capabilities to support augmentation. Identifying these missing capabilities is the first step towards an intelligent system. The next is extending the platforms to deliver these capabilities.

Analytics, Augmentation, Automation and Adaptation

 

We need to acknowledge the differences between data science, machine learning and artificial intelligence. By understanding these differences we can clearly define and demonstrate the path from analytics to adaptive intelligence systems. While data analytics can deliver excellent insight into the underlying business dynamics, true artificial intelligence will only be demonstrated when systems can leverage the full suite of techniques and tools of AI within a framework that supports the application of augmentation, automation and finally adaptive methods.

To explore this in more detail, let us try to describe what we mean by the four ‘A’s, however, there needs to be some caution, as we note that each one has some overlap with adjacent layers of the pyramid. The top of the pyramid is Analytics, and is equivalent to the tip of the iceberg. The bottom of the pyramid, is adaptive systems, this being the most sophisticated of the four ‘A’s and the most complex to deliver, but with the most significant benefits. Augmentation and Automation are stepping stones from Analytics to Adaptive Systems, but necessary steps that each can be demonstrated to show benefit to the business while providing the opportunity for the business to gain confidence of the systems put in place.

What we are seeing across many industries, is a focus on leveraging big data platforms and data lakes by applying just data science techniques in the form of data analytics. It seems that at the moment, few if any companies realise the power of a platform that not only delivered advanced data analytics and visualisation, but can help them on the journey to produce fully automated and adaptive intelligence systems. Such systems could support entire business processes, freeing up staff to focus on more complex tasks, leaving the automated systems to cover the high volume simpler tasks.

Hopefully some of the companies that are currently building the tools and frameworks that are currently available are planning to deliver more advanced platforms in the future, However, unfortunately at the moment it appears that companies are not producing the platforms and frameworks that are needed to support the development of all four ‘A’s. This seems to be a huge missed opportunity, and should be avoided if we want to prevent the AI field stalling again (avoiding the third AI Winter).

What needs to happen next is to deliver platforms that can augment manual workflow by providing semi-automated systems that support business process and enable the subject matter experts to focus on the more involved and complex elements of the business process. Moving this platform forward to a point where the majority of the process is fully automated would add significant benefit to any business workflow. The bottom layer of the pyramid, is adaptation, and this is where we get fully enabled intelligent systems that can adapt to changes in the underlying data and continue to perform at the level of performance when the system was initially introduced.

I would like to see this pyramid referenced for the development of machine learning frameworks and artificial intelligence platforms, to guide the type of capabilities being build and deployed.

We should not just strive to build data analytics, but produce intelligent systems that can augment and automate business process in a way that adapts to changes in the data space over time providing systems that continue to deliver performant automation.
