Access. Accessible. Accessibility. Right of Access (GDPR).


Through a technological lens, mapped with efficiency and with AI, ‘accessible’ could refer to the ease with which data, applications, and services can be accessed and used by machines, without human intervention. This could imply the absence of a ‘human-in-the-loop.’

Such a system is one that could be optimized for efficiency and that could perform tasks quickly, accurately, and reliably.

From an interface design, mapped with consequentialist ethical perspectives, an accessible AI system could suggest that users, with empowering considerations of their abilities, vulnerabilities or disabilities, could access and use the system with ease or with means nuanced to their specific needs.

It could also refer to the degree to which a product, service, or technology is available, affordable, and designed to meet the needs of all individuals, including those from marginalized or otherwise disenfranchised  communities.

Degrees of accessibility implies that access could not be or be less constraint due to demographics, background, abilities, or socioeconomic status. This definition of accessibility could imply some of the following concepts which could improve due to accessibility, and that to some degree: agency, autonomy, plurality, diversity and diversification, equity, personalization, inclusivity, fairness, mindfulness, and compassion. Through such perspective this could be considered a ‘good’ system design. This could then lead one to consider concepts such as ‘ethical-by-design,’

An accessible AI  system could then also be one that is transparent (the lack of transparency implies a lack of access, even if it is access to the possibility of understanding the inner workings of the AI system), and thus of concepts such as, explainable, and accountable, ensuring that the decisions made by the AI system are fair, unbiased, and aligned with ethical principles.

The Right of Access (GDPR)’ is one of the 8 rights of the individual user (also referred to as “data subjects”) as defined within the European Union’s General Data Protection Regulation (GDPR). It is article 15 in the GDPR: “The data subject shall have the right to obtain from the controller confirmation as to whether or not personal data concerning him or her are being processed, and, where that is the case, access to the personal data…” and access to a number of categories of information as further defined in this article.

This policy item aims “to empower individuals and give them control over their personal data.” The 8 rights are “the right of access, the right to rectification, the right to erasure, the right to restrict processing, the right to data portability, the right to object and the right not to be subject to a decision based solely on automated processing.

“You shall know a word by the company it keeps.”

– Krohn, J.[1]

Definitions are artificial meaning-giving constructs. A definition is a specific linguistic form with a specific function. Definitions are patterns of weighted attributes, handpicked by means of (wanted and unwanted) biases. A definition is then as a category of attributes referring to a given concept and which then, in turn, aims at triggering a meaning of that targeted concept.

Definitions are aimed at controlling such meaning-giving of what it could refer to and of what it can contain within its proverbial borders: the specified attributes, narrated into a set (i.e. a category), that makes up its construct as to how some concept is potentially understood.

The preceding sentences could be seen as an attempt to a definition of the concept “definition” with a hint of how some concepts in the field of AI itself are defined (hint: have a look at the definitions of “Artificial Neural Networks” or of “Machine Learning” or of “Supervised and Unsupervised Learning”). Let us continue looking through this lens and expand on it.

Definitions can be constructed in a number of ways. For instance: they can be constructed by identifying or deciding on, and giving a description of, the main attributes of a concept. This could be done, for instance, by analyzing and describing forms and functions of the concept. Definitions could, for instance, be constructed by means of giving examples of usage or application; by stating what some concept is (e.g. synonyms, analogies) and is not (e.g. antonyms); by referring to a historical or linguistic development (e.g. its etymology, grammatical features, historical and cultural or other contexts, etc.); by comparison with other concepts in terms of similarities and differentiators; by describing how the concept is experienced and how not; by describing its needed resources, its possible inputs, its possible outputs, intended aims (as a forecast), actual outcome and larger impact (in retrospect). There are many ways to construct a definition. So too is it with a definition for the concept of “Artificial Intelligence”.

For a moment, as another playful side-note, by using our imagination and by trying to make the link between the process of defining and the usage of AI applications stronger: one could imagine that an AI solution is like a “definition machine.”

One could following imagine that this machine gives definition to a data set –by offering recognized patterns from within the data set– at its output. This AI application could be imagined as organizing data via some techniques.  Moreover, the application can be imagined to be collecting data as if attributes of a resulting pattern. To the human receiver this in turn could then define and offer meaning to a selected data set . Note, it also provides meaning to the data that is not selected into the given pattern at the output. For instance: the date is labelled as “cat” not “dog” while also some data has been ignored (by filtering it out; e.g. the background “noise” of ‘cat’).  Did this imagination exercise allow one to make up a definition of AI? Perhaps. What do you think? Does this definition satisfy your needs? Does it do justice to the entire field of AI from its “birth”, its diversification process along the way, to “now”? Most likely not.

A human designer of a definition likely agrees with the selected attributes (though not necessarily) while, those receiving the designed definition might agree that it offers a pattern but, not necessarily the meaning-giving pattern they would construct. Hence, definitions tend to be contested, fine-tuned, altered, up-dated, dismissed all-together over time and, depending on the perspective, used to review and qualify other yet similar definitions.  It almost seems that some definitions have a life of their own while others are, understandably, safely guarded to be maintained over time.

When learning about something and when looking a bit deeper than a surface, one then quickly is presented with numerous definitions of what was thought to be one and the same thing yet, which show variation and diversity in a field of study. This is OK. We, as individuals within our species, are able to handle, or at least live with ambiguities, uncertainties and change. These, by the way, are also some of the reasons why, for instance and to some extent, the fields of Statistics, Data Science and AI (with presently the sub-field of Machine Learning and Deep Learning) exist.

The “biodiversity” of definitions can be managed in many ways. One can manage different ideas at the same time in one’s head. It is as one can think of black and white and a mix of the two, in various degrees and that done simultaneously; while also introducing a plethora of additional colors. This can still offer harmony in one’s thinking. If that doesn’t work, one can put more importance to one definition over another, depending on some parameters befitting the aim of the learning and the usage of the definition (i.e. one’s practical bias of that moment in spacetime). One can prefer to start simple, with a reduced model as offered in a modest definition while (willingly) ignoring a number of attributes. This one could remind oneself to do so by not equating this simplified model / definition with the larger complexities of that what it only initiates to define.

One can apply a certain quality standard to allow the usage of one definition over another. One could ask a number of questions to decide on a definition. For instance: Can I still find out who made the definition? Was this definition made by an academic expert or not, or is it unknown? Was it made a long time ago or not; and is it still relevant to my aims? Is it defining the entire field or only a small section? What is intended to be achieved with the definition?  Do some people disagree with the definition; why? Does this (part of the) definition aid me in understanding, thinking about or building on the field of AI or does it rather give me a limiting view that does not allow me to continue (a passion for) learning? Does the definition help me initiate creativity, grow eagerness towards research, development and innovation in or with the field of AI? Does this definition allow me to understand one or other AI expert’s work better? If one’s answer is satisfactory at that moment, then use the definition until proven inadequate. When inadequate, reflect, adapt and move on.

With this approach in mind, the text here offers further 10 considerations and “definitions” on the concept of “Artificial Intelligence”. For sure, others and perhaps “better” ones can be identified or constructed.


“AI” Definitions & Considerations

#1 An AI Definition and its Issues.
The problem with many definitions of Artificial Intelligence (AI) is that they are riddled with what is called “suitcase words”. They are “…terms that carry a whole bunch of different meanings that come along even if we intend only one of them. Using such terms increases the risk of misinterpretations…”.[2] This term, “suitcase words”, was created by a world-famous computer scientist, who is considered one of the leading figures in the developments of AI technologies and the field itself: Professor MINSKY, Marvin.

#2 The Absence of a Unified Definition.
On the global stage or among all AI researchers combined, there is no official (unified) definition of what Artificial Intelligence is. It is perhaps better to state that the definition is continuously changing with every invention, discovery or innovation in the realm of Artificial Intelligence. It is also interesting to note that what was once seen as an application of AI is (by some) now no longer seen as such (and sometimes “simply” seen as statistics or as a computer program like any other). On the other end of the spectrum, there are those (mostly non-experts or those with narrowed commercial aims) who will identify almost any computerized process as an AI application.

#3 AI Definitions and its Attributes.
Perhaps a large number of researchers might agree that an AI method or application has been defined as “AI” due to the combination of the following 3 attributes:

it is made by humans or it is the result of a technological process that was originally created by humans,

it has the ability to operate autonomously (without the support of an operator; it has ‘agency’[3]) and

it has the ability to adapt (behaviors) to, and improve within changing contexts (i.e. changes in the environment); and this by means of a kind of technological process that could be understood as a process of “learning”. Such “learning” can occur in a number of ways. One way is to “learn” by trial-and-error or a “rote learning” (e.g. the storing in memory of a solution to a problem). A more complex way of applying “learning” is by means of “Generalization”. This means the system can “come up” with a solution, by generalizing some mathematical rule or set of rules from given examples (i.e. data), to a problem that was previously not yet encountered. The latter would be more supportive towards being adaptable in changing and uncertain environments.

#4 AI Definitions by Example.
Artificial Intelligence could, alternatively, also be defined by listing examples of its applications and methods. As such some might define AI by listing its methods (which are individual methods in the category of AI methods. Also see here below one of the listing of types and methods towards defining the AI framework): AI than, for instance, includes Machine Learning, Deep Learning and so on.

Others might define AI by means of its applications whereby AI is, for instance, a system that can “recognize”, locate or identify specific patterns or distinct objects in (extra-large, digital or digitized) data sets where such data sets could, for instance, be an image or a video of any objects (within a set), a set or string of (linguistic) sounds, be it prerecorded or in real-time, via a camera or other sensor. These objects could be a drawing, some handwriting, a bird sound, a photo of a butterfly, a person uttering a request, a vibration of a tectonic plate, and so on (note: the list is, literally, endless).

#5 AI Defined by referencing Human Thought.
Other definitions define AI as a technology that can “think” as the average humans do (yet, perhaps, with far more processing power and speed)… These would be “…machines with minds, in the full and literal sense… [such] AI clearly aims at genuine intelligence, not a fake imitation.[4] Such a definition creates AI research and developments driven by “observations and hypothesis about human behavior”; as it is done in the empirical sciences.[5]. At the moment of this writing, the practical execution of this definition has not yet been achieved.

#6 AI Defined by Referencing Human Actions.
Further definitions of what AI is, do not necessarily focus on the aspect of ability of thought. Rather some definitions for AI focus on the act that can be performed by an AI technology. Then definitions are something like: an AI application is a technology that can act as the average humans can act or do things with perhaps far more power, strength, speed and without getting tired, bored, annoyed or hurt by features of the act or the context of the act (e.g. work inside a nuclear reactor). Rai Kurzweil, a famous futurist and inventor in technological areas such as AI, defined the field of AI as: “ The art of creating machines that perform functions that require intelligence when performed by people.[6] 

#7 Rational Thinking at the Core of AI Definitions.
Different from the 5th definition is that thought does not necessarily have to be defined through a human lens or anthropocentrically. As humans we tend to anthropomorphize some of our technologies (i.e. give a human-like shape, function, process, etc. to a technology). Though, AI does not need to take on a human-like form, function nor process; unless we want it to. In effect, an AI solution does not need to take on any corporal / physical form at all. An AI solution is not a robot; it could be embedded into a robot.

One could define the study of AI as a study of “mental faculties through the use of computational models.”[7] Another manner of defining the field in this way is stating that it is the study of the “computations that make it possible to perceive, reason and act.”[8] [9]

The idea of rational thought goes all the way back to Aristotle and his aim to formalize reasoning. This could be seen as a beginning of logic. This was adopted early on as one of the possible methods in AI research towards creating AI solutions. It is, however, difficult to implement. This is the case since not everything can be expressed in a formal logic notation and not everything is perfectly certain. Moreover, not all problems are practically solvable by logic principles, even if via such logic principles they might seem solved.[10]

#8 Rational Action at the Core of AI Definitions.
A system is rational if “it does the ‘right thing’, given what it knows.” Here, a ‘rational’ approach is an approach driven by mathematics and engineering. As such “Computational Intelligence is the study of the design of intelligent agents…”[11] To have ‘agency’ means to have the autonomous ability and to be enabled to act / do / communicate with the aim to perform a (collective) task.[12] Scientists, with this focus in the field of AI, research “intelligent behavior in artifacts”.[13]

Such AI solution that can function as a ‘rational agent’ applies a form of logic reasoning and would be an agent that can act according to given guidelines (i.e. input) yet do so autonomously, adapt to environmental changes, work towards a goal (i.e. output) with the best achievable results (i.e. outcome) over a duration of time and this in a given (changing) space influenced by uncertainties. The application of this definition would not always result in a useful AI application. Some complex situations would, for instance, be better to respond to with a reflex rather than with rational deliberation. Think about a hand on a hot stove…[14] 

#9 Artificial Intelligence methods as goal-oriented agents.
Artificial Intelligence methods as goal-oriented agents. “Artificial Intelligence is the study of agents that perceive the world around them, form plans, and make decisions to achieve their goals. Its foundations include mathematics, logic, philosophy, probability, linguistics, neuroscience and decision theory.”[15]

#10 AI Defined by Specific Research and Development Methods.
We can somewhat understand the possible meaning of the concept “AI” by looking at what some consider the different types or methods of AI, or the different future visions of such types of AI (in alphabetic order)[16]:

Activity Recognition

  • a system that knows what you are doing and acts accordingly. For instance: it senses that you carry many bags, so it automatically opens the door for you (without you needing to verbalize the need).

Affective Computing

  • a system that can identify the emotion someone showcases

Artificial Creativity

  • A system that can output something that is considered creative (e.g. a painting, a music composition, a written work, a joke, etc.)

Artificial Immune System

  • A system that functions in the likes of a biological immune system or that mimics its processes of learning and memorizing.

Artificial Life

  • A system that models a living organism

Artificial Stupidity

  • A system that adapts to the intellectual capacity of the form (life form, human) it interacts with or to the needs in a given context.

Automation

  • The adaptable mechanical acts coordinated by a system without the intervening of a human

Blockhead

  • A “fake” AI that simulates intelligence by referencing (vast) data repositories and regurgitating the information at the appropriate time. This system however does not learn.

Bot

  • A system that functions as a bodiless robot

ChatBot / ChatterBot

  • A system that can communicate with humans via text or speech giving the perception to the human (user) that it is itself also human. Ideally it would pass the Turing test.

Committee Machine

  • A system that combines the output from various neural networks. This could create a large-scale system.

Computer Automated Design

  • A system that can be put to use in areas of creativity, design and architecture that allow and need automation and calculation of complexities

Computer Vision

  • A system that via visual data can identify (specific) objects

Decision Support System

  • A system that adapts to contextual changes and supports human decision making

Deep Learning

  • A system operating on a sub-type of Machine Learning methods (see a future blog post for more info)

Embodied Agent

  • A system that operates in a physical or simulated “body”

Ensemble Learning

  • A system that applies many algorithms for learning at once.

Evolutionary Algorithms

  • A system that mimics biological evolutionary processes: birth, reproduction, mutation, decay, selection, death, etc. (see a future blog post for more info)

Friendly Artificial Intelligence

  • A system that is void of existential risk to humans (or other life forms)

Intelligence Amplification

  • A system that increases human intelligence

Machine Learning

  • A system of algorithms that learns from data sets and which is strikingly different from a traditional program (fixed by its code). (see a future blog post for more info)

Natural Language Processing

  • A system that can identify, understand and create speech patterns in a given language. (see a future blog post for more info)

Neural Network

  • A system that historically mimicked  a brain ‘s structure and function (neurons in a network) though now are driven by statistical and signal processing. (see another of my blog post for more info here)

Neuro Fuzzy

  • A system that applies a neural network to operate in a or fuzzy logic as a non-linear logic, or a non-Boolean logic (values between 0 or 1 and not only 0 or 1). It allows for further  interpretation of vagueness and uncertainty

Recursive Self-Improvement

  • A system that allows for software to write its own code in cycles of self-improvement.

Self-replicating Systems

  • A system that can copy itself (hardware and or software copies). This is researched for (interstellar) space exploration.

Sentiment Analysis

  • A system that can identify emotions and attitudes imbedded into human media (e.g. text)

Strong Artificial Intelligence

  • A system that has a general intelligence as a human does. This is also referred to as AGI or Artificial General Intelligence. This does not yet exist and might, if we continue to pursuit it, take decades to come to fruition. When it does it might start a recursive self-improvement and autonomous reprogramming, creating an exponential expansion in intelligence well beyond the confines of human understanding. (see a future blog post for more info)

Superhuman

  • A system that can do something far better than humans can

Swarm Intelligence

  • A system that can operate across a large number of individual (hardware) units and organizes them to function as a collective

Symbolic Artificial Intelligence

  • An approach used between 1950 and 1980 that limits computations to the manipulation of a defined set of symbols, resembling a language of logic.

Technological Singularity

  • A hypothetical system of super-intelligence and rapid self-improvement out of the control and beyond the understanding of any human. 

Weak Artificial Intelligence

  • A practical system of singular or narrow applications, highly focused on a problem that needs a solution via learning from given and existing data sets. This is also referred to as ANI or Artificial Narrow Intelligence.
