Intelligent Agents and Environments

Intelligent agents are crucial in understanding Artificial Intelligence. They can perceive their environment, act upon it, learn from experiences, and can be categorized based on their complexity and capabilities. The PEAS framework provides a method to define the components of an agent's environment and tasks, emphasizing the importance of rationality and autonomy in agent behavior.

    Rationality And Autonomy

    This section discusses the concepts of rationality and autonomy in intelligent agents, explaining how they make decisions and learn independently.

    Learning Practice

  • 2.3.1

    Rationality

    Rationality in intelligent agents refers to their capability of acting to achieve the best expected outcome based on their environmental knowledge.

    Learning Practice

  • 2.3.2

    Autonomy

    Autonomy refers to the ability of an agent to operate independently and learn from its environment without external intervention.
