A
percept is the input that an
intelligent agent is
perceiving at any given moment. It is essentially the same concept as a
percept in
psychology, except that it is being perceived not by the
brain but by the agent. A percept is detected by a
sensor, often a
camera, processed accordingly, and acted upon by an
actuator. Each percept is added to a
percept sequence, which is a complete history of each percept ever detected. An
intelligent agent chooses how to act not only based on the current percept, but the percept sequence. The next action is chosen by the agent function, which maps every percept to an action.
