An intelligent agent (IA) is an entity that makes a decision, enables artificial intelligence to be put into action. It can also be described as a software entity that conducts operations in the place of users or programs after sensing the environment. It uses actuators to initiate action in that environment.
This agent has some level of autonomy that allows it to perform specific, predictable, and repetitive tasks for users or applications.
It’s also termed ‘intelligent’ because of its ability to learn during the process of performing tasks.
