The modern definition of artificial intelligence (or AI) is “research and development of intelligent agents”, where an intelligent agent is a system that perceives the environment and performs actions that maximize its chances of success.
John McCarthy, who coined the term in 1956, defines it as “the science and technique of making intelligent machines.”
Other names for this area have been proposed, such as computational intelligence, synthetic intelligence, or computational rationality.
The term artificial intelligence is also used to describe a property of machines or programs: the intelligence that a system exhibits.
Research in artificial intelligence uses tools and ideas from many fields, including computer science, psychology, philosophy, neuroscience, cognitive science, linguistics, operations research, economics, control theory, probability, optimization and logic.
AI research also intersects with tasks like robotics, control systems, planning, data mining, logistics, voice recognition, facial recognition, and many others.
