nowadays, artificial intelligence, which is becoming more and more familiar with us with the development of science and technology, is infiltrating into our daily life gradually, and it brings great convenience and progress to our society. although we don't have a great knowledge about the specific content of artificial intelligence, we enjoy the convenience and benefit that artificial intelligence brings to us. we can say that artificial intelligence is changing the way of our living, learning, working and so on.artificial intelligence can be ed as a new science and technology, which is used to simulate human intelligence. namely, computers simulate the way of human's thinking and intelligent behavior, such as learning, reasoning, thinking, planning, and so on. we can't deny the fact that artificial intelligence is of great application nowadays. for example, a lot ofintelligent computer or household appliances come into our life, intelligent robots help us to finish some difficult work that we can't do by ourselves, and intelligent control has improved our working greatly. we can say that artificial intelligence exists everywhereas one of the three most cutting-edge technologies in twenty-first century, artificial intelligence has a very bright prospect. however, the biggest obstacle of it is that it is a subject, which is related to computer science. psychology. philosophy and other knowledge. 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. future trends in computer science is one of the artificial intelligence,it is the research and artificial simulation of human thought and eventually be able to make a human like to think the same machine.for human services and to help people solve problems. after all, people thought it was unique, there are feelings, there are a variety of character, this will be very difficult to achieve in the machine.in fact, to do the same as the human thinking machine, the only one of the artificial intelligence, is by no means all. through the study of artificial intelligence, can resolve all kinds of scientific problems, and promote the development of other science, the artificial intelligence is the best! i believe that the science of artificial intelligence is waiting for humanity to explore it step by step the real connotation.
