1、 Artificial intelligencenArtificial intelligence is to use computers to analog and instead of human brain . The advent of computers has made artificial intelligence a major breakthrough. The computer can not only replace some of the human brain function, but exceed the human brain greatly in speed a
2、nd accuracy .It can not only simulate part of analysis and the comprehensive function, but is getting to display a certain characteristics of consciousness. It really became an extension of the human brain.What is AI?The exciting new effort to make computers thinks machine with minds, in the full an
