Study Notes
Agent Types and Environments
- There are 9 types of agents: Table driven Agent, Simple reflex agents, Model-based reflex agents, Goal-based agents, Utility-based agents, Learning Agent, Intelligent Agents, Mobile Agent, and Multi-Agent Systems (MAS)
Simple Reflex Agents
- Operate based on a simple "if-then" rule format
- Take actions based on the current percept or input without considering past states or future consequences
Model-based Reflex Agents
- Maintain an internal model or representation of the world
- Use this model to make decisions by considering past states, current percepts, and anticipated future states
Goal-based Agents
- Have predefined goals or objectives that guide their decision-making process
- Take actions that are expected to move them closer to achieving their goals
Utility-based Agents
- Make decisions by evaluating the utility or desirability of different actions
- Choose actions that maximize their expected utility or reward
Learning Agents
- Can adapt and improve their behavior over time through learning mechanisms
- Acquire knowledge and skills from experience, feedback, and training data
Agents and Environments
- An agent perceives its environment through sensors and acts upon it through actuators
- The agent function maps from percept histories to actions
- The agent program implements the agent function
Rational Agent
- Does the right thing based on the performance measure
- Chooses actions that maximize the expected value of the performance measure
- Limited by the available percepts and lacks knowledge of the environment dynamics
PEAS (Performance measure, Environment, Actuators, Sensors)
- A framework for specifying the task environment
- Used to design a rational agent
- Consists of Performance measure, Environment, Actuators, and Sensors
Examples of PEAS
- Automated taxi system
- Medical diagnosis system
- Pac-man game
