Overview of artificial intelligence,电信*-* 曲*电信*-* 邵*,人工智能,Have you ever seen these movies?,These movies are all regarding to something about artificial intelligence. But those are fiction, they are both have the robot characters. So it makes AI sound a little fictional to us. In fact, AI is not just about robots, it exists everywhere.,Dictionaries define intelligence as the ability to acquire, understand and apply knowledge, or the ability to exercise thought and reason. Of course intelligence is more than this. It embodies all of the knowledge and feats, both conscious and unconscious, which we have acquired through studying.,What is artificial intelligence exactly?,Systems that think like humans,Systems that act like humans,Systems that think rationally,Systems that act rationally,Views of AI fall into four categories:,The exciting new effort to make computers thinks machine with minds, in the full and literal sense” (Haugeland 1985),“The study of mental faculties through the use of computational models” (Charniak et al. 1985),“The art of creating machines that perform functions that require intelligence when performed by people” (Kurzweil, 1990),A field of study that seeks to explain and emulate intelligent behavior in terms of computational processes” (Schalkol, 1990),Main Goal of AI, Represent and store knowledge（表示并存储知识）, Retrieve and reason about knowledge（知识检索和思考）, Behave intelligently in complex environments（在复杂环境中表现智能）, Develop interesting and useful applications（开发有趣和有用的应用程序）, Interact with people, agents, and the environment（与人，机构，环境相交流）,Foundations of AI,AI,ComputerScience & Engineering,Philosophy,Biology,Linguistics,CognitiveScience,Psychology,Economics,Mathematics,Engineering: To get machines to do a wider variety of useful things, e.g., understand spoken natural language, recognize individual people in visual scenes, find the best travel plan for your vacation, Cognitive Science: As a way to understand how natural minds and mental phenomena work, e.g., memory, learning, language, visual perception.,Philosophy: As a way to explore some basic and interesting (and important) philosophical questions ,e.g., the mind body problem, what is consciousness.,What Can AI Systems Do Now?,Here are some example applications:,Robots（机器人）,Face Recognition（人脸识别）,Intelligent Control（智能控制）,Genetic Programming(基因工程）,Planning and scheduling（计划和调度）,What Cant AI Systems Do?,Understand natural language robustly 熟练理解自然语言,Surf the web (or a wave)网上冲浪,Interpret an arbitrary visual scene解释一个任意的视觉场景,Learn a natural language学习一种自然语言,Refocus attention in complex environments复杂环境中重新集中注意,Perform life-long learning执行终身学习,Artificial intelligence benefits us in the following aspects:, Artificial intelligence like computers or robots can improve productivity and efficiency., Human labors are liberated from dull or dangerous job., Artificial intelligence offers much convenience to human life., Artificial intelligence can turn all human dreams into reality with the promotion of science and technology., Entertaining us,What dose the difference between the artificial intelligence and human beings?,All the artificial intelligence is created by human beings.,Artificial intelligence have solved some small problems which people could have solved in other ways.,Artificial intelligence are not living organisms, so it cannot have feelings.,AgreeRobots have replaced human beings in many aspects of work that people do, especially the dangerous work and some housework.This will probably happen gradually over a period of time, but it is an inevitable trend.,DisagreeRobots can only replace humans in doing some jobs, but: Made by people No human characteristics,Will robots ever be able to replace people?,Summarize,Artificial intelligence can be scripted as a new science and technology, which is used to simulate human intelligence. We cant deny the fact that artificial intelligence is of great important nowadays. Therefore, what we should do is to study hard, widen our knowledge, and consolidate our professional knowledge. Only by this way can we do contribution to the development of artificial intelligence and the improvement of our lives.,校对：曲* 邵*演讲：曲* 邵*,Thank you!,
