Unifying the Cognitive Sciences: The Free Energy Principle

Karl Friston · 1:18:47

Building on feedback control, this lecture introduces the Free Energy Principle as a more general framework, explaining how biological systems minimize prediction error to maintain their existence and adapt to their environment.

The Physics of Communication

Karl Friston · 1:30:15

This lecture extends the Free Energy Principle to the domain of communication, demonstrating how information exchange can be understood as a process of minimizing free energy, thus linking perception, action, and interaction.
