What is artificial intelligence...?
« on: December 27, 2014, 11:13:05 AM »

Artificial intelligence (AI) A branch of computer science that was pursued with great optimism in the 1960s and 70S, in an attempt to make computers think more like human beings. It analyzes data and draw conclusions in a way that makes them appear to be "intelligent." Now of course, computers can't think or do anything without being told what to do. So AI programs use complex formulas which attempt to arrive at an answer in a method similar to how a human might do it.

Some AI programs attempt to simulate the way humans think, while others try to mimic an expert with years of experience. Two AI categories that deal with the way humans think are fuzzy logic and neural networks. Fuzzy logic programs take into account the fact that input is not always precise sometimes input requires a judgment.

For example, an average traffic light turns red or green for a given period of time, regardless of the traffic flow. However, if the traffic light contained an AI computer using fuzzy logic, it could judge when to change the light based on the flow of traffic. The AI computer would not make a decision based on exactly how many cars were passing through the intersection, but rather, on whether that traffic was considered "heavy" or "light." Because traffic flow varies, the AI computer would examine the changing number of cars and make a judgment on when to change the light.
