Understanding PEAS in Artificial Intelligence

1. Performance Measure: Performance measure is the unit to define the success of an agent.Performance varies with agents based on their different precept.

2. Environment: Environment is the surrounding of an agent at every instant. It keeps changing with time if the agent is set in motion.There are 5 major types of environments:

· Fully Observable & Partially Observable

· Episodic & Sequential

· Static & Dynamic

· Discrete & Continuous

· Deterministic & Stochastic

3. Actuator: Actuator is a part of the agent that delivers the output of an action to the environment.

4. Sensor: Sensors are the receptive parts of an agent which takes in the input for the agent.
