An Overview of Artificial Intelligence

Abstract

Artificial Intelligence (AI) is also Machine Intelligence (MI) is intelligence demonstrated by machine in contrast to the “Natural Intelligence” (NI) displayed by human and other animals. In computer science, all research is defined as the study of “Intelligent agent”: any device that perceives its environment and takes actions that maximize its change of successfully achieving its goal .The “Artificial Intelligence” is applied when a machine mimics “cognitive” function that human associate with other human minds such as “learning and problem solving”. AI is behavior of a machine, which, if performed by a human being, would be called intelligent. It makes machines smarter and more useful, and is less expensive than natural intelligence. Natural language processing (NLP) refers to artificial intelligence methods of communicating with a computer in a natural language like English. The main objective of a NLP program is to understand input and initiate action. Artificial intelligence involves two basic ideas. First, it involves studying the thought processes of human beings. Second, it deals with representing those processes via machines (like computers, robots, etc.).
