Artificial intelligence (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 rules to reach
approximate or definite conclusions) and self-correction. Particular applications of AI include expert systems, speech recognition and machine vision.AI can be categorized as either weak or strong.
Weak AI, also known as narrow AI, is an AI system that is designed and trained for a particular task.
