Artificial Intelligence

Intelligence is the computational part of the ability to achieve goals in the world. Varying kinds and degrees of intelligence occur in people, many animals and some machines.
Artificial Intelligence (AI) is the area of computer science focusing on creating machines that can engage on behaviors that humans consider intelligent. The ability to create intelligent machines has intrigued humans since ancient times and today with the advent of the computer and 50 years of research into Artificial Intelligence programming techniques, the dream of smart machines is becoming a reality. Researchers are creating systems which can mimic human thought, understand speech, beat the best human chess player, and countless other feats never before possible.

Artificial Intelligence, in today’s world, is used in many activities in many sub-fields. Some of the applications of Artificial Intelligence are game playing, speech recognition system, understanding natural language, autonomous planning and scheduling, robotics and many more fields.

One significant use of artificial intelligence is in the field of designing expert system. Expert system is such a system which can work, understand like humans and also having a superior knowledge about the purpose with which it has been built. As an example first expert system designed MYCIN can be taken. MYCIN was able to diagnosed bacterial infections of the blood and also able to suggest required treatment. It did better than medical students or practicing doctors, provided its limitations were observed.
