Study Notes
External World Uncertainty
- Agents operate in an environment, which is an external world
- The state of the external world is often unknown
- Agents build a world model through observations and interactions with the environment
- The world model is imperfect and incomplete
World Model Uncertainty
- The world model is based on incomplete and noisy sensory data
- There is inherent uncertainty in the world due to factors such as:
- Limited Sensors: Sensors have limitations and cannot perceive everything with certainty
- Occlusion: Objects can be hidden from view
- Ambiguity: Objects can look similar, leading to misinterpretation
- Unpredictable Events: Unexpected events can occur, changing the environment without notice
Sensor Limitations
- Sensors have limited range and resolution
- They are sensitive to noise and can be inaccurate
- They cannot perceive everything
- Sensors are designed for specific tasks and may miss crucial information
Ambiguity and Uncertainty
- Multiple possible interpretations can exist for a single sensor reading
- This creates ambiguity and makes it difficult to determine the true state of the world
- Uncertainty arises from incomplete information and limitations in perception
- The agent's world model is constantly being updated and refined, as more information becomes available
Agent's Inability
- Agents can never be completely certain about the state of the external world because of inherent limitations
- Sensors provide an incomplete and noisy representation of the environment, making it impossible to have perfect knowledge
- Unpredictable events contribute to uncertainty and change the situation
