What is Artificial Intelligence? (cont.) “The science and engineering of making intelligent machines, especially intelligent computer programs.” “The business of getting computers to do things they cannot already do, or things they can only do in movies and science fiction stories.” “The study of how to make computers do things at which, at the moment, lb t t people are better.” “The design of flexible programs that respond productively in situations that were not specifically anticipated by the designer.” “The construction of computations that perceive, reason, and act effectively in uncertain environments.” “The branch of CS concerned with enabling computers to simulate such aspects of human intelligence as speech recognition, deduction, inference, creative response, the ability to learn from experience, and the ability to make inferences given incomplete information.” odeling aspects of human cognition on computers” Modeling aspects of human cognition on computers “What AI people do” 3

Herb Simon John McCarthy Allen Newell Marvin Minsky Seminal event for AI as a field, in 1956: The Dartmouth Summer Research Conference on Artificial Intelligence e propose that a 2 month 10 man study of artificial intelligence be carried out We propose that a 2 month, 10 man study of artificial intelligence be carried out during the summer of 1956 at Dartmouth College in Hanover, New Hampshire. The study is to proceed on the basis of the conjecture that every aspect of learning or any other feature of intelligence can in principle be so precisely described that a machine can be made to simulate it. An attempt will be made to find how to make machines use language, form abstractions and concepts, solve kinds of problems now reserved for humans, and improve themselves. We think at a significant advance can be made in one or more of these problems if a that a significant advance can be made in one or more of these problems if a carefully selected group of scientists work on it together for a summer.” 4
