Artificial intelligence
The ability of a computer or other machine to perform actions thought to require intelligence. Among these actions are logical deduction and inference, creativity, the ability to make decisions based on past experience or insufficient or conflicting information, and the ability to understand spoken language.
Did You Know? One laboratory devoted to research on artificial intelligence explains what they do: "Our goal is to understand the nature of intelligence and to engineer systems that exhibit intelligence." You may think of a computer as smart, but it is actually just following directions very fast. A truly intelligent device would be more flexible and would engage in the kind of "thinking" that people really do. An example is vision. A network of sensors combined with systems for interpreting the data may produce the kind of pattern recognition that we take for granted as seeing and understanding what we see. In fact, developing software that can recognize subtle differences in objects (such as those we perceive in the faces of two people) is very difficult. Differences that we can perceive without deliberate effort require massive amounts of data and careful guidelines for a system of artificial intelligence to recognize. Computers are necessary to artificial intelligence because they allow researchers to manage all the data needed to try to imitate true intelligence. The attempt to create artificial intelligence should lead to a better understanding of the human brain. After all, you can't copy it if you don't know how it works.
