Artificial intelligence

Artificial intelligence is "the study and design of intelligent agents" where an intelligent agent is a system that perceives its environment and takes actions which maximize its chances of success.

There are two main schools of thought, Strong AI, and Weak AI.

Strong AI is the approach that aims to duplicate human intellectual abilities. Weak AI aims at simulating human intelligence, however, does not achieve a level of human intelligence. Examples of weak AI are Siri and IBM Watson; they only function successfully when applied to specific tasks.
