Artificial Intelligence
Formal
A technology that gives computers the ability to learn based on data, previous experiences, and their environment to make decisions to maximize results. AI is the simulation of human intelligence processes by machines, especially computer systems.
Practical
AI is the simulation of human intelligence processes by machines, especially computer systems. These processes include learning (the acquisition of information and rules for using the information), reasoning (using the rules to reach approximate or definite conclusions) and self-correction. Particular applications of AI include expert systems, speech recognition and machine vision.
