　　Address of Welcome

　　It is a great honor that professor Li is here to give us a lecture on computer science. Mr. Li is a prominent professor of Jiaotong University. He has been engaged in AI research for many years and has achieved a great success inthis area.

　　Computer is one of the greatest inventions in the 20th century. Since it came into being, the computer science, especially AI has developed rapidly and has changed our world radically. Due to its ability to think, memorize and with its amazing calculating speed, the computer is put to wide use in industry, agriculture, business, education and tourism. It is now widely believed that a person who has no computer literacy is like illiteracy in the past.

　　Today, we are very happy to have invited professor Li to deliver a speech on the future development of AI. I am sure his lecture will benefit all of us. Now let’s give him a big clap.
