    Study Notes

    AI Agents Overview

    • AI systems focus on rational agents that sense and act within their environments.
    • Agents utilize sensors for observation and actuators for action.

    Types of Agents

    • Human-Agent: Uses sensory organs (eyes, ears) and actuators (hands, legs).
    • Robotic Agent: Employs cameras, infrared sensors, and motors.
    • Software Agent: Operates through keystrokes and file contents, displays output through screens.

    Devices of Agents

    • Sensors: Detect environmental changes, providing information to electronic devices.
    • Actuators: Convert energy into motion, responsible for system movement (e.g., electric motors).
    • Effectors: Physical devices that influence the environment (e.g., wheels, legs).

    Real-Time Example: Automatic Door

    • Motion Sensor: Detects presence of individuals approaching the door.
    • Electric Motor: Controls door movement based on sensor signals.

    Decision Making in Agents

    • Employs climate control algorithms to optimize comfort while minimizing energy consumption.
    • Balances conflicting goals and weighs the likelihood of success against goal importance.

    Learning Agents

    • Incorporate a learning element to enhance knowledge over time.
    • Use feedback to adjust performance, improving accuracy and effectiveness.

    Components of Learning Agents

    • User Input (Sensor): Collects commands via microphone or text.
    • Internal Model (User Preferences & Context): Tracks preferences for personalized interactions.
    • Learning Element: Utilizes machine learning to enhance capabilities.
    • Performance Element: Executes tasks based on the current state.
    • Critic: Evaluates agent actions through user satisfaction.

    Four Fundamental Rules for AI Agents

    • Must perceive the environment.
    • Utilize observations for decision-making.
    • Resultant decisions lead to actions.
    • Actions must be rational and logical.

    Types of AI Agents

    • Reflex Agents: Respond immediately to stimuli without considering past states; rely on the event-condition-action rule.

      • Real-Time Example: Automatic Light Switch, which activates with motion detection and deactivates when no motion is sensed.
      • Limitations: Very basic intelligence and lack of knowledge about non-perceptual state aspects.
    • Model-based Agents: Utilize a more extensive view of the environment to inform their actions unlike reflex agents.
