Study Notes
Environment Types
- In a fully observable environment, everything an agent requires to choose its actions is available to it via its sensors.
- Partially observable environments involve uncertainty in the next state.
- In a fully observable environment, the current percept suffices for taking action.
Agent Characteristics
- An agent is an entity that perceives its environment and takes actions to achieve a goal.
- Examples of sensors for a human agent include eyes, ears, and skin.
- The agent function maps from percepts to actions.
Agent Program
- The role of the agent program is to take input from sensors and output actions.
Rationality
- A rational agent needs to know the performance measure, the environment, the agent's current state, and the actions available to it in order to perform well.
- Rationality is different from perfection, as it involves making the best decision given the available information, rather than making the optimal decision.
Autonomy
- The autonomy of an agent refers to its ability to make its own decisions and take actions based on those decisions.
Task Environment
- To define a task environment for an intelligent agent design, four items are needed: performance measure, environment, actuators, and sensors.
- PEAS stands for Performance, Environment, Actuators, and Sensors in the context of intelligent agent design.
Application-Specific Environments
- The performance measure of an Interactive English tutor agent is to engage the student in a conversation.
- The main environment faced by a Medical diagnosis System agent is the medical domain.
Additional Examples
- In the simplified map of Romania demo, percepts include the current location and the actions are moving to a new location.
This quiz covers the concept of agents and environments in artificial intelligence, including different types of agents and environments. It also explores the notion of rationality in the context of PEAS (Performance measure, Environment, Actuators, Sensors).
