Free Energy Principle — Karl Friston
Serious Science・10 minutes read
The Free Energy Principle explains how systems maximize Bayesian model evidence to maintain existence, particularly in the brain where internal states model the world to achieve this. It serves as an organizing principle for living systems, connecting different brain theories and enabling hypothesis generation about brain processes.
Insights
- The Free Energy Principle is a foundational concept in systems neuroscience that explains how living systems maintain their existence by maximizing Bayesian model evidence.
- By utilizing the concept of a Markov blanket to separate internal and external states, the Free Energy Principle provides insights into brain organization, such as the distinction between different streams in processing information.
