Study Notes

AI Agents

Agents sense and act upon their environment using sensors and effectors.
Human Agents use eyes, ears, hands, and other body parts as sensors and effectors.
Robotic Agents use cameras, infrared range finders as sensors, and motors as effectors.
Software Agents use encoded bit strings.

Rational Agents

Rational Agents perform the right action to maximize their success.
Performance measures can be misleading.
Performance measure should consider:
- Long-term goals
- Perceptual history
- Agent's knowledge
- Actions the agent can perform
Ideal Rational Agents perform the actions to maximize their performance measure based on their knowledge and sensory input.

Intelligent Agent Requirements

Autonomy: The agent's behavior is determined by its experience.
Built-in Knowledge: Agents may have a base understanding of the environment.

Environment Types

Fully Observable vs. Partially Observable: An agent can see the entire environment, or only part of it.
Deterministic vs. Stochastic: The future state of the environment is predictable, or it is unpredictable.
Discrete vs. Continuous: The environment has a finite number of states, or the states are in a continuous range.
Episodic vs. Sequential: The agent's actions in one episode have no effect on future episodes, or the agent's past actions impact the future.
Static vs. Dynamic: The environment is unchanging, or it is changing while the agent is making a decision.

Agent Programs

Agent Program: Maps percepts to actions.
Architecture: The computer or hardware the agent program runs on.
Designing Effective Agent Programs involves understanding:
- Percepts and actions
- Goals and performance measures
- The agent's operating environment

Agent Program Types

Simple Reflex Agents: Act based on current percept, without memory of past experiences.
Goal-Based Agents: Use goals to guide their action selection, considering the future.
Utility-Based Agents: Use utility functions to evaluate and compare possible states and actions.
