1. The capability of a device to perform functions that are normally associated with human intelligence, such as reasoning, learning, and self‑improvement. 2. Research and study in methods for the development of a machine that can improve its own operations. The development or capability of a machine that can proceed or perform functions that are normally associated with human intelligence, as learning, adapting, reasoning, self‑correction, automa­tic improvement. 3. The study of computer and related techniques to supplement the in­tellectu­al capabilities of man. As man has invented and used tools to increase his physical powers, he now is beginning to use artificial intelligence to increase his mental powers. In a more restric­ted sense, the study of techniques for more effective use of digital computers by improved programming techniques.
