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.

Computing, Life, and Intelligence

Blaise Agüera y Arcas · 1:23:05

Transitioning from theoretical principles, this lecture explores the practical implications of these ideas by examining the emergence of digital life and intelligence, connecting theoretical biology with computer science.

What is Ultimately Real? Consciousness, Free Energy, and Spacetime

Donald Hoffman & Karl Friston · 2:40:25

This culminating lecture engages with the most profound implications of active inference and the Free Energy Principle, exploring how these frameworks challenge our understanding of consciousness, spacetime, and the ultimate nature of reality.
