Episode notes
Free Energy Principle
- The free energy principle, like Hamilton's principle, describes self-organizing systems.
- It explains how systems settle into preferred states, like cereal in a box.
Brain as a Model
- Our brains model the causal structure of the world through neuronal connections.
- This model allows us to predict and interact with our environment.
Active Inference
- Active inference is the application of the free energy principle to behavior.
- Perception is unconscious inference based on actively sought data from our environment.
