Artificial Intelligence is the branch of computer sciences that emphasizes the development of intelligence machines, thinking and working like humans. Artificial intelligence makes it possible for machines to learn from experience, adjust to new inputs and perform human-like tasks.The traditional problems (or goals) of AI research include reasoning, knowledge representation, planning, learning, natural language processing, perception and the ability to move and manipulate objects, artificial intelligence (AI), sometimes called machine intelligence, is intelligence demonstrated by machines, unlike the natural intelligence displayed by humans and animals. Leading AI textbooks define the field as the study of "intelligent agents": any device that perceives its environment and takes actions that maximize its chance of successfully achieving its goals.
