Artificial intelligence (AI) is the simulation of human intelligence processes by machines, especially computer systems. These processes include learning, reasoning, and self-correction. AI aims to create intelligent machines that can perform tasks like speech recognition, learning, planning, problem solving, and manipulating objects. Research in AI is highly technical and focuses on programming computers with traits like knowledge, reasoning, problem solving, perception, learning, and planning. It also involves areas like machine learning, knowledge engineering, classification, machine perception, and robotics.
