- 3. Introduction to AI Thebranch of computer science concerned with making computers behave like humans. The term was coined in 1956 by John McCarthy at the Massachusetts Institute of Technology. Artificial intelligence includes :- games playing: programming computers to play games such as chess and checkers . expert systems : programming computers to make decisions in real-life . natural language : programming computers to understand natural human languages .
- 4. Introduction to AI neural networks : Systems that simulate intelligence by attempting to reproduce the types of physical connections that occur in animal brains . robotics : programming computers to see and hear and react to other sensory stimuli . Currently, no computers exhibit full artificial intelligence (that is, are able to simulate human behavior).
- 5. Introduction of ExpertSystem In arterial intelligent an expert system is a computer system that emulates the decision –making ability of a human expert . Expert system are designed to solve complex problems by resoning about knowledge , like a expert. Do not follow the procedure of a developer as the case in convectional programming Divided into two parts , one fixed in depended of the expert system : the inference , and one variable : the knowledge base. In the 80s a third part appeared : a dialog interface to communicate with users. This ability to conduct a conversation with users was latter called “conversational” .
