Artificial intelligence (AI) is a branch of computer and information science. The goal of AI is to create a machine that behaves like an ordinary man with an improved machine behaviour in tackling complex tasks and to accomplish tasks that if accomplished by humans would be considered a display of intelligence. The field of AI includes studying and developing machines such as robots, automatic pilots for airplanes and space ships, and military weapons. Europeans tend to use the term Machine Intelligence (MI) instead of the term AI.
