- 2. CONTENTS Agents and Environments Good Behavior: The concept of Rationality
- 3. AGENT An agent is anything that can be viewed as perceiving its environment through sensors and acting upon that environment through actuators. Consider the example of human as agent and eyes, ear for sensors and hands, leg for actuators. We can consider even robotics and software as agents.
- 4. Percept: It refers to the agents perceptual inputs at any given instant. Percept sequence: Complete history of everything the agent has ever perceived.
- 5. Agents interact with environment through sensors and actuators Enviro nment Agents Sensors Actuators Percept Actions
- 6. AGENT FUNCTION Mathematically, we say that agent’s behavior is described by the agent function that maps any given percept to an action. It is abstract mathematical description. AGENT PROGRAM It is a implementation, running within some physical system
- 7. GOOD BEHAVIOR:THE CONCEPT OF RATIONALITY Rational agent: It is the one that does the right thing. Every entry in the table for the agent function is filled out correctly. Performance measure: Sequences of actions causes the environment to go through a sequence of states.If the sequence is desirable then the agent has performed well. It evaluates the any sequence of environment states.
- 8. Rationality Rational at any given time depends on four things The performance measure that defines the criterion of success. The agents prior knowledge of the environment. The actions that the agent can perform. The agents percept sequence to date.
- 9. DEFINITION OF RATIONAL AGENT For each possible percept sequence, a rational agent should select an action that is expected to maximize its performance measure, given the evidence provided by the percept sequence and whatever built-in knowledge the agent has.
- 10. OMNISCIENCE Omniscient agent knows the actual outcome of its actions and can act accordingly;but omniscience is impossible in reality. INFORMATION GATHERING Doing actions in order to modify future percepts is called as information gathering.
- 11. AUTONOMY Agent relies on the prior knowledge of its designer rather than on its own percepts,we say that agent lacks autonomy. A Rational agent not only gather information but also learn as much as possible from what it perceives. Agents initial configuration reflect the prior knowledge of the environment. LEARNING
