General intelligence (the ability to solve an arbitrary problem) is among the field's long-term goals.

The traditional goals of AI research include reasoning, knowledge representation, planning, learning, natural language processing, perception and the ability to move and manipulate objects. The various sub-fields of AI research are centered around particular goals and the use of particular tools. In the first decades of the 21st century, highly mathematical statistical machine learning has dominated the field, and this technique has proved highly successful, helping to solve many challenging problems throughout industry and academia. AI research has tried and discarded many different approaches during its lifetime, including simulating the brain, modeling human problem solving, formal logic, large databases of knowledge and imitating animal behavior. Īrtificial intelligence was founded as an academic discipline in 1956, 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. For instance, optical character recognition is frequently excluded from things considered to be AI, having become a routine technology. Īs machines become increasingly capable, tasks considered to require 'intelligence' are often removed from the definition of AI, a phenomenon known as the AI effect. Tesla), and competing at the highest level in strategic game systems (such as chess and Go).

Google), recommendation systems (used by YouTube, Amazon and Netflix), understanding human speech (such as Siri or Alexa), self-driving cars (e.g. ĪI applications include advanced web search engines (i.e. Some popular accounts use the term 'artificial intelligence' to describe machines that mimic 'cognitive' functions that humans associate with the human mind, such as 'learning' and 'problem solving', however this definition is rejected by major AI researchers. Leading AI textbooks define the field as the study of ' intelligent agents': any system that perceives its environment and takes actions that maximize its chance of achieving its goals.

Artificial intelligence ( AI) is intelligence demonstrated by machines, as opposed to the natural intelligence displayed by humans or animals.
