Machines understand verbal commands, distinguish pictures, drive cars and play games better than we do.
Artificial intelligence AI is intelligence demonstrated by machines , unlike the natural intelligence displayed by humans and animals , which involves consciousness and emotionality.
The distinction between the former and the latter categories is often revealed by the acronym chosen. Leading AI textbooks define the field as the study of " intelligent agents ": any device that perceives its environment and takes actions that maximize its chance of successfully achieving its goals.
As machines become increasingly capable, tasks considered to require "intelligence" are often removed from the definition of AI, a phenomenon known as the AI effect. Artificial intelligence was founded as an academic discipline in , and in the years since has experienced several waves of optimism,   followed by disappointment and the loss of funding known as an " AI winter " ,   followed by new approaches, success and renewed funding.
The traditional problems or goals of AI research include reasoning , knowledge representation , planning , learning , natural language processing , perception and the ability to move and manipulate objects.
Many tools are used in AI, including versions of search and mathematical optimization, artificial neural networks, and methods based on statistics, probability and economics. The AI field draws upon computer science , information engineering , mathematics , psychology , linguistics , philosophy , and many other fields. The field was founded on the assumption that human intelligence "can be so precisely described that a machine can be made to simulate it". These issues have been explored by myth , fiction and philosophy since antiquity.
In the twenty-first century, AI techniques have experienced a resurgence following concurrent advances in computer power , large amounts of data , and theoretical understanding; and AI techniques have become an essential part of the technology industry , helping to solve many challenging problems in computer science, software engineering and operations research. The study of mechanical or "formal" reasoning began with philosophers and mathematicians in antiquity. The study of mathematical logic led directly to Alan Turing 's theory of computation , which suggested that a machine, by shuffling symbols as simple as "0" and "1", could simulate any conceivable act of mathematical deduction.
This insight, that digital computers can simulate any process of formal reasoning, is known as the Church—Turing thesis. Turing proposed changing the question from whether a machine was intelligent, to "whether or not it is possible for machinery to show intelligent behaviour". The field of AI research was born at a workshop at Dartmouth College in ,  where the term "Artificial Intelligence" was coined by John McCarthy to distinguish the field from cybernetics and escape the influence of the cyberneticist Norbert Wiener.
Marvin Minsky agreed, writing, "within a generation They failed to recognize the difficulty of some of the remaining tasks. Progress slowed and in , in response to the criticism of Sir James Lighthill  and ongoing pressure from the US Congress to fund more productive projects, both the U. The next few years would later be called an " AI winter ",  a period when obtaining funding for AI projects was difficult.
In the early s, AI research was revived by the commercial success of expert systems ,  a form of AI program that simulated the knowledge and analytical skills of human experts. By , the market for AI had reached over a billion dollars. At the same time, Japan's fifth generation computer project inspired the U.
S and British governments to restore funding for academic research. Mead and Mohammed Ismail. In the late s and early 21st century, AI began to be used for logistics, data mining , medical diagnosis and other areas. In , in a Jeopardy! AlphaGo was later improved, generalized to other games like chess, with AlphaZero ;  and MuZero  to play many different video games , that were previously handled separately,  in addition to board games. Other programs handle imperfect-information games; such as for poker at a superhuman level, Pluribus poker bot  and Cepheus poker bot.
According to Bloomberg's Jack Clark, was a landmark year for artificial intelligence, with the number of software projects that use AI within Google increased from a "sporadic usage" in to more than 2, projects. Clark also presents factual data indicating the improvements of AI since supported by lower error rates in image processing tasks.
By , Natural Language Processing systems such as the enormous GPT-3 then by far the largest artificial neural network were matching human performance on pre-existing benchmarks, albeit without the system attaining commonsense understanding of the contents of the benchmarks.
Computer science defines AI research as the study of " intelligent agents ": any device that perceives its environment and takes actions that maximize its chance of successfully achieving its goals. A typical AI analyzes its environment and takes actions that maximize its chance of success. Goals can be explicitly defined or induced. If the AI is programmed for " reinforcement learning ", goals can be implicitly induced by rewarding some types of behavior or punishing others. AI often revolves around the use of algorithms.
An algorithm is a set of unambiguous instructions that a mechanical computer can execute. A simple example of an algorithm is the following optimal for first player recipe for play at tic-tac-toe : . Many AI algorithms are capable of learning from data; they can enhance themselves by learning new heuristics strategies, or "rules of thumb", that have worked well in the past , or can themselves write other algorithms. Some of the "learners" described below, including Bayesian networks, decision trees, and nearest-neighbor, could theoretically, given infinite data, time, and memory learn to approximate any function , including which combination of mathematical functions would best describe the world.
In practice, it is seldom possible to consider every possibility, because of the phenomenon of " combinatorial explosion ", where the time needed to solve a problem grows exponentially. Much of AI research involves figuring out how to identify and avoid considering a broad range of possibilities unlikely to be beneficial.
The earliest and easiest to understand approach to AI was symbolism such as formal logic : "If an otherwise healthy adult has a fever, then they may have influenza ". A second, more general, approach is Bayesian inference : "If the current patient has a fever, adjust the probability they have influenza in such-and-such way".
A fourth approach is harder to intuitively understand, but is inspired by how the brain's machinery works: the artificial neural network approach uses artificial " neurons " that can learn by comparing itself to the desired output and altering the strengths of the connections between its internal neurons to "reinforce" connections that seemed to be useful.
These four main approaches can overlap with each other and with evolutionary systems; for example, neural nets can learn to make inferences, to generalize, and to make analogies. Some systems implicitly or explicitly use multiple of these approaches, alongside many other AI and non-AI algorithms; the best approach is often different depending on the problem. Learning algorithms work on the basis that strategies, algorithms, and inferences that worked well in the past are likely to continue working well in the future.
These inferences can be obvious, such as "since the sun rose every morning for the last 10, days, it will probably rise tomorrow morning as well".
Learners also work on the basis of " Occam's razor ": The simplest theory that explains the data is the likeliest. Therefore, according to Occam's razor principle, a learner must be designed such that it prefers simpler theories to complex theories, except in cases where the complex theory is proven substantially better. Settling on a bad, overly complex theory gerrymandered to fit all the past training data is known as overfitting. Many systems attempt to reduce overfitting by rewarding a theory in accordance with how well it fits the data, but penalizing the theory in accordance with how complex the theory is.
A toy example is that an image classifier trained only on pictures of brown horses and black cats might conclude that all brown patches are likely to be horses. Modifying these patterns on a legitimate image can result in "adversarial" images that the system misclassifies.
This enables even young children to easily make inferences like "If I roll this pen off a table, it will fall on the floor". Humans also have a powerful mechanism of " folk psychology " that helps them to interpret natural-language sentences such as "The city councilmen refused the demonstrators a permit because they advocated violence" A generic AI has difficulty discerning whether the ones alleged to be advocating violence are the councilmen or the demonstrators   .
This lack of "common knowledge" means that AI often makes different mistakes than humans make, in ways that can seem incomprehensible. For example, existing self-driving cars cannot reason about the location nor the intentions of pedestrians in the exact way that humans do, and instead must use non-human modes of reasoning to avoid accidents.
The cognitive capabilities of current architectures are very limited, using only a simplified version of what intelligence is really capable of. For instance, the human mind has come up with ways to reason beyond measure and logical explanations to different occurrences in life. What would have been otherwise straightforward, an equivalently difficult problem may be challenging to solve computationally as opposed to using the human mind.
This gives rise to two classes of models: structuralist and functionalist. The structural models aim to loosely mimic the basic intelligence operations of the mind such as reasoning and logic.
The functional model refers to the correlating data to its computed counterpart. The overall research goal of artificial intelligence is to create technology that allows computers and machines to function in an intelligent manner. The general problem of simulating or creating intelligence has been broken down into sub-problems. These consist of particular traits or capabilities that researchers expect an intelligent system to display.
The traits described below have received the most attention. Early researchers developed algorithms that imitated step-by-step reasoning that humans use when they solve puzzles or make logical deductions. These algorithms proved to be insufficient for solving large reasoning problems because they experienced a "combinatorial explosion": they became exponentially slower as the problems grew larger. They solve most of their problems using fast, intuitive judgments.
Knowledge representation  and knowledge engineering  are central to classical AI research. Some "expert systems" attempt to gather explicit knowledge possessed by experts in some narrow domain. In addition, some projects attempt to gather the "commonsense knowledge" known to the average person into a database containing extensive knowledge about the world.
Among the things a comprehensive commonsense knowledge base would contain are: objects, properties, categories and relations between objects;  situations, events, states and time;  causes and effects;  knowledge about knowledge what we know about what other people know ;  and many other, less well researched domains. A representation of "what exists" is an ontology : the set of objects, relations, concepts, and properties formally described so that software agents can interpret them.
The semantics of these are captured as description logic concepts, roles, and individuals, and typically implemented as classes, properties, and individuals in the Web Ontology Language. Such formal knowledge representations can be used in content-based indexing and retrieval,  scene interpretation,  clinical decision support,  knowledge discovery mining "interesting" and actionable inferences from large databases ,  and other areas.
Intelligent agents must be able to set goals and achieve them. In classical planning problems, the agent can assume that it is the only system acting in the world, allowing the agent to be certain of the consequences of its actions.
This calls for an agent that can not only assess its environment and make predictions but also evaluate its predictions and adapt based on its assessment. Multi-agent planning uses the cooperation and competition of many agents to achieve a given goal. Emergent behavior such as this is used by evolutionary algorithms and swarm intelligence.
Machine learning ML , a fundamental concept of AI research since the field's inception, [d] is the study of computer algorithms that improve automatically through experience. Unsupervised learning is the ability to find patterns in a stream of input, without requiring a human to label the inputs first. Supervised learning includes both classification and numerical regression , which requires a human to label the input data first.
Classification is used to determine what category something belongs in, and occurs after a program sees a number of examples of things from several categories. Regression is the attempt to produce a function that describes the relationship between inputs and outputs and predicts how the outputs should change as the inputs change. Computational learning theory can assess learners by computational complexity , by sample complexity how much data is required , or by other notions of optimization.
The agent uses this sequence of rewards and punishments to form a strategy for operating in its problem space. Natural language processing  NLP allows machines to read and understand human language. A sufficiently powerful natural language processing system would enable natural-language user interfaces and the acquisition of knowledge directly from human-written sources, such as newswire texts. Some straightforward applications of natural language processing include information retrieval , text mining , question answering  and machine translation.
Modern statistical NLP approaches can combine all these strategies as well as others, and often achieve acceptable accuracy at the page or paragraph level. Machine perception  is the ability to use input from sensors such as cameras visible spectrum or infrared , microphones, wireless signals, and active lidar , sonar, radar, and tactile sensors to deduce aspects of the world. Applications include speech recognition ,  facial recognition , and object recognition. Such input is usually ambiguous; a giant, fifty-meter-tall pedestrian far away may produce the same pixels as a nearby normal-sized pedestrian, requiring the AI to judge the relative likelihood and reasonableness of different interpretations, for example by using its "object model" to assess that fifty-meter pedestrians do not exist.
Artificial intelligence AI makes it possible for machines to learn from experience, adjust to new inputs and perform human-like tasks. Most AI examples that you hear about today — from chess-playing computers to self-driving cars — rely heavily on deep learning and natural language processing. Using these technologies, computers can be trained to accomplish specific tasks by processing large amounts of data and recognizing patterns in the data. The term artificial intelligence was coined in , but AI has become more popular today thanks to increased data volumes, advanced algorithms, and improvements in computing power and storage. Early AI research in the s explored topics like problem solving and symbolic methods. In the s, the US Department of Defense took interest in this type of work and began training computers to mimic basic human reasoning.

In this paper we offer a formal definition of Artificial Intelligence and this directly gives us an algorithm for construction of this object. Really, this algorithm is useless due to the combinatory explosion. The main innovation in our definition is that it does not include the knowledge as a part of the intelligence. So according to our definition a newly born baby also is an Intellect.
Artificial Intelligence, if even the term intelligence itself is difficult to define? The precise definition and meaning of the word intelligence, and even more so of.
The intelligence demonstrated by machines is known as Artificial Intelligence. It is the simulation of natural intelligence in machines that are programmed to learn and mimic the actions of humans. These machines are able to learn with experience and perform human-like tasks. As technologies such as AI continue to grow, they will have a great impact on our quality of life.
Artificial intelligence AI , the ability of a digital computer or computer-controlled robot to perform tasks commonly associated with intelligent beings. The term is frequently applied to the project of developing systems endowed with the intellectual processes characteristic of humans, such as the ability to reason, discover meaning, generalize, or learn from past experience. Since the development of the digital computer in the s, it has been demonstrated that computers can be programmed to carry out very complex tasks—as, for example, discovering proofs for mathematical theorems or playing chess —with great proficiency.
What is artificial intelligence AI? And are the technologies that we have today really reflective of all that this term implies? Traditionally a branch of computer science, AI as a holistic concept has pulled from many areas of academic arenas, from philosophy to physics. Intelligence is often dependent on context. We include this as a preface for helping to distinguish between the two in our present state of technological development. It is related to the similar task of using computers to understand human intelligence, but AI does not have to confine itself to methods that are biologically observable.

Отключить все это без подготовки - значит парализовать разведдеятельность во всем мире. - Я отдаю себе отчет в последствиях, сэр, - сказал Джабба, - но у нас нет выбора. - Объясните, - потребовал Фонтейн. Он посмотрел на Сьюзан, стоявшую рядом с ним на платформе. Казалось, все происходящее было от нее безумно .
Я могу прямо сейчас отвести вас в участок… - Беккер выразительно замолчал и прищелкнул пальцами. - Или?. - спросил немец с расширившимися от страха глазами. - Или мы придем к соглашению. - Какому соглашению? - Немец слышал рассказы о коррупции в испанской полиции.
Это было все равно что установить жучки во все телефонные аппараты на земле. Стратмор попытался убедить Танкадо, что ТРАНСТЕКСТ - это орудие охраны правопорядка, но безуспешно: Танкадо продолжал настаивать на том, что это грубейшее нарушение гражданских прав. Он немедленно уволился и сразу же нарушил Кодекс секретности АНБ, попытавшись вступить в контакт с Фондом электронных границ. Танкадо решил потрясти мир рассказом о секретной машине, способной установить тотальный правительственный контроль над пользователями компьютеров по всему миру. У АН Б не было иного выбора, кроме как остановить его любой ценой.
Они были вмонтированы так хитро, что никто, кроме Грега Хейла, их не заметил, и практически означали, что любой код, созданный с помощью Попрыгунчика, может быть взломан секретным паролем, известным только АНБ. Стратмору едва не удалось сделать предлагаемый стандарт шифрования величайшим достижением АНБ: если бы он был принят, у агентства появился бы ключ для взлома любого шифра в Америке. Люди, знающие толк в компьютерах, пришли в неистовство.
