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.
