What Is the Definition of Artificial Intelligence? (AI) How Does Artificial Intelligence Work?

What Is the Definition of Artificial Intelligence?

Artificial intelligence (AI) is a vast branch of computer science concerned with the development of intelligent machines capable of doing tasks that would typically need human intelligence. 

AI is an interdisciplinary subject with numerous methodologies, but developments in machine learning and deep learning are driving a paradigm shift in practically every sector of the technology industry.

 

Machine learning enables machines to model and improve the capabilities of the human mind. AI is becoming more common in everyday life, from self-driving cars to the growth of smart assistants like Siri and Alexa. 

As a result, numerous technology companies across a wide range of industries are investing in artificially intelligent technologies.

What Exactly Is AI?

Less than a decade after assisting the Allies in winning World War II by breaking the Nazi encryption machine Enigma, mathematician Alan Turing transformed history once more with a simple question: "Can machines think?"

 

Turing's 1950 work "Computing Machines and Intelligence" and the Turing Test that followed established the essential purpose and vision of AI.

 

At its core, artificial intelligence (AI) is the discipline of computer science that seeks an affirmative response to Turing's challenge. It is an attempt to recreate or recreate human intelligence in robots. The broad goal of AI has produced a slew of challenges and debates. To the point that no single definition of the field is generally recognized.

AI Definition

The primary drawback of describing AI as simply "creating intelligent machines" is that it does not explain what AI is or what makes a machine intelligent. AI is an interdisciplinary subject with several methodologies, but developments in machine learning and deep learning are driving a paradigm change in practically every sector of the technology industry.

However, several other tests have lately been developed that have gotten generally positive feedback, including a 2019 research paper titled "On the Measure of Intelligence." François Chollet, a senior deep learning researcher, and Google engineer argues in the study that intelligence is the "pace at which a learner converts its experience and priors into new skills at worthwhile tasks that incorporate ambiguity and adaption." In other words, the most intelligent algorithms can use the limited experience to anticipate the result of a wide range of situations.

 

Meanwhile, authors Stuart Russell and Peter Norvig address the subject of AI in their book Artificial Intelligence: A Contemporary Approach by uniting their work around the theme of intelligent agents in machines.

 

Norvig and Russell then look into four distinct artificial intelligence methodologies that have historically defined the field:

 

The first two concepts deal with cognitive processes and thinking, whereas the remainder deals with behavior. Norvig and Russell are particularly interested in rational agents who act to maximize their chances of success, stating that "all of the skills required for the Turing Test also allow an agent to act rationally."

 

While these ideas may look esoteric to the average person, they help to focus the subject as a branch of computer science and give a road map for incorporating machine learning and other subsets of artificial intelligence into machines and programs.

 

 

The AI Future

When one considers the computing costs and the technical data infrastructure that supports artificial intelligence, it is clear that implementing AI is a complicated and costly endeavor. Thankfully, tremendous advances in computing technology have occurred, as seen by Moore's Law, which claims that the number of transistors on a microchip doubles roughly every two years while the cost of computers is halved.

 

Although many experts anticipate Moore's Law will stop somewhere in the 2020s, it has had a significant impact on present AI approaches – without it, deep learning would be financially impossible. According to recent studies, AI innovation has exceeded Moore's Law, doubling every six months or so rather than every two years.

 

According to that logic, artificial intelligence has made significant advances in a range of areas during the previous several years. And the possibility of an even greater influence over the next several decades appears all but certain.

 

Artificial Intelligence's Four Types

AI is classified into four categories based on the type and complexity of jobs that a system can execute. Automated spam filtering, for example, belongs to the most fundamental class of AI, whereas the far-off possibility of robots that can comprehend people's thoughts and feelings belongs to an altogether separate AI subset.

 

Reactive Machines

 

A reactive machine adheres to the most fundamental AI principles and, as the name suggests, is only capable of using its intellect to observe and react to the world in front of it. Because a reactive machine lacks memory, it cannot depend on prior experiences to influence real-time decision-making.

 

Because reactive machines perceive the world immediately, they are only designed to do a few specialized tasks. Yet, intentionally reducing a reactive machine's worldview is not a cost-cutting tactic; rather, it means that this type of AI will be more trustworthy and reliable — it will respond consistently to the same stimuli.

 

Deep Blue, a chess-playing supercomputer created by IBM in the 1990s that defeated international expert Gary Kasparov in a game, is a well-known example of a reactive machine. Deep Blue could only identify the pieces on a chess board and know how each moves according to the rules of chess, as well as recognize each piece's current position and determine what the most logical move would be at that time.

 

The computer was not anticipating prospective moves by its opponent or attempting to better place its own pieces. Every turn was regarded as its own reality, apart from any previous movements.

 

Google's AlphaGo is another example of a reactive game-playing AI. AlphaGo is likewise incapable of predicting future moves, instead relying on its own neural network to assess current game developments, giving it an advantage over Deep Blue in a more complex game. AlphaGo has also defeated world-class Go players, including champion Lee Sedol in 2016.

 

While limited in scope and difficult to modify, reactive machine Intelligence can achieve a level of complexity and reliability when designed to perform recurring tasks.

 

Limited Memory

By gathering information and considering prospective options, AI with limited memory can preserve previous facts and forecasts – effectively peering into the past for indications of what may happen next. AI with limited memory is more complicated and has more potential than reactive computers.

 

Memory limitations AI is developed when a team regularly trains a model to analyze and use fresh data, or when an AI environment is built to allow models to be automatically trained and renewed.

 

Six actions must be taken when using restricted memory AI in ML: The training data must be created, the ML model must be formed, the model must be capable of making predictions, the model must be capable of receiving human or environmental feedback, that feedback must be recorded as data, and these processes must be repeated in a cycle.

 

Theory of Mind

Theoretical psychology is exactly that: theoretical. We have not yet developed the technological and scientific capabilities required to reach this next level of artificial intelligence.

 

The concept is based on the psychological premise that other living creatures have thoughts and feelings that influence one's own actions. This would imply that AI machines may know how people, animals, and other machines feel and make decisions through self-reflection and determination, and then use that information to make their own conclusions.

 

Machines would essentially have to be able to grasp and process the concept of "mind," the changes of emotions in decision-making, and a slew of other psychological concepts in real-time, establishing two-way communication between people and AI.

 

Self-Awareness

After the theory of mind has been established, AI will be able to become self-aware at some point in the future. This type of AI has human-level consciousness and recognizes its own presence in the world, as well as the presence and emotional condition of others. It would be able to grasp what others may require based not only on what they convey to them but also on how they communicate it.

 

Self-awareness in AI is dependent on human researchers comprehending the concept of consciousness and then discovering how to replicate it so that it may be incorporated into machines.
