Episode notes
Perception for Action
- Perception is for interacting with the environment, not just for knowing it.
- It guides action and helps us navigate and engage with the world.
The Problem with Representations
- Indirect perception creates a disconnect between perception and action by introducing mediating representations.
- Action then has to work its way back out to the world, creating unnecessary complexity.
Importance of Specifying Information
- Specifying information (information_L) is crucial for direct perception.
- Information must be lawfully structured to guarantee directness and to allow perception and action coupling.
