Study Notes
Agents and Environments
- An agent is anything that can perceive its environment through sensors and act upon it through effectors.
- Examples of agents include human agents, robotic agents, and software agents.
- The agent function maps percepts to actions.
- An agent program runs on the physical architecture to produce the agent function.
Intelligent Agents
- An intelligent agent is a software entity that senses its environment and carries out operations with autonomy, employing representation of the user's goal.
- An agent can be a program or a robot.
Vacuum-Cleaner World
- A vacuum-cleaner agent perceives the environment and performs actions based on the perceived state of the environment (e.g., location and dirt status).
- The agent function maps percept sequences to actions.
- The agent program is the internal implementation of the agent function.
Rational Agents
- Rational agents strive to choose actions that maximize their performance measure.
- The performance measure is an objective criterion for success.
- Rationality is distinct from omniscience (all-knowing).
- Agents engage in information gathering and exploration to modify future percepts for better decision making.
- Autonomous agents learn and adapt based on their experiences.
Characteristics of Agents
- Agents are autonomous, persistent, adaptive, mobile, and have learning capabilities.
Specifying the Task Environment
- PEAS: Performance measure, Environment, Actuators, Sensors is a useful framework for designing rational agents.
- The PEAS framework helps in describing the task environment for designing agents.
- Example: An automated taxi needing to consider performance measure (safe, fast, legal trip), the environment (roads, traffic, weather), actuators (steering wheel, accelerator), and sensors (cameras, speedometer).
