Artificial intelligence 人工智能 deep blue深蓝 美国IBM公司生产的一台超级国际象棋电脑 1997 年 5 月 11 日，在人与计算机之间挑战赛的历史上可以说是历史性的一天。计算机在正常时限的比赛中首次击败了等级分排名世界第一的棋手。加里·卡斯帕罗夫以 2.5:3.5 输给 IBM 的计算机程序 “深蓝”。 For years,reseachers have been exploring the way people think in hopes of creating a computer that thinks likes a person. However ,no agreement exists about what artificial intelligence is. If a computer that can collect ,choose among , understand , perceive, and know,then we have artificial intelligence. AI is the science of making machines do things that would require intelligence if done by a person. 《人工智能》 Why do the definition differ? First of all,there is no and never has been a single agreed-on definition of human intelligence. Second,consensus on the point at which a machine exhibits intelligence is difficulty to achieve. When a computer could play tic-tac-toe,some reseachers considered it to be intelligent because it could choose the next best possible move and could beat its human opponents. Other characteristics have been added to our definition of intelligent behavior--the ability to reason logically and respond creatively to problems. What is AI supposed to do? The aim of AI is to produce a generation of systems that will be able to communicate with us by speech and hearing ,use ”vision” (scanning) that approximates the way people see ,and be capable of intelligent problems solving. What is AI supposed to do Robotic Natural language processing Artificial reality Robotic According to Webster’s Ninth Collegiate Dictionary , a robot is an automatic device that performs functions ordinarily ascribed to human being or that operates with what appears to be almost human intelligence. Robotic In the field of artificial intelligence , there are intelligent robots (also called perception robots) and unintelligent robots. Robot Intelligent robot Unintelligent robot Robotic Most robots are unintelligent; that is they are programmed to do specific tasks, and they are incapable of
