Study Notes
Agent Types
1. Simple Reflex Agent
- Reacts to the current state of the environment
- No internal state or memory
- Acts based on the current percept (input)
2. Model-Based Reflex Agent
- Maintains an internal model of the environment
- Uses the model to make decisions
- Can reason about the current state of the environment
3. Goal-Based Agent
- Has specific goals to achieve
- Uses the current state of the environment and goals to make decisions
- Can reason about the current state of the environment and goals
4. Utility-Based Agent
- Makes decisions based on a utility function
- The utility function assigns a value to each possible state of the environment
- Chooses the action that maximizes the expected utility
5. Learning Agent
- Can learn from experience and improve its performance over time
- Uses reinforcement learning, inductive learning, or other learning techniques
- Can adapt to changing environments and tasks
6. Hybrid Agent
- Combines different agent types to achieve a specific goal
- Can integrate different architectures and techniques
- Can adapt to complex and dynamic environments
Key Characteristics
- Autonomy: Agents make decisions and act independently
- Perception: Agents perceive the environment and react to it
- Reasoning: Agents use reasoning and decision-making techniques to make decisions
- Actuation: Agents can affect the environment through actions
- Learning: Agents can learn and improve over time
Agent Types
- Simple Reflex Agent: Reacts to the current environment state, has no internal state or memory, and acts based on the current percept (input).
Model-Based Reflex Agent
- Maintains an internal model of the environment, uses the model to make decisions, and can reason about the current state of the environment.
Goal-Based Agent
- Has specific goals to achieve, uses the current environment state and goals to make decisions, and can reason about the current state of the environment and goals.
Utility-Based Agent
- Makes decisions based on a utility function, which assigns a value to each possible environment state, and chooses the action that maximizes the expected utility.
Learning Agent
- Can learn from experience and improve its performance over time, uses reinforcement learning, inductive learning, or other learning techniques, and can adapt to changing environments and tasks.
Hybrid Agent
- Combines different agent types to achieve a specific goal, integrates different architectures and techniques, and can adapt to complex and dynamic environments.
