Artificial intelligence (AI) is intelligence exhibited by machines. In computer science, an “intelligent” machine is a flexible rational agent. It perceives its environment, interacts, learns. The term “artificial intelligence” is applied when a machine mimics “cognitive” functions such as “learning” and “problem solving”. Capabilities currently classified as AI include successfully understanding human speech,competing at a high level in strategic game systems (such as Chess and Go), self-driving cars, and interpreting complex data.
