The History and Unreasonable Effectiveness of Feedback Control

Karl Johan Åström · 1:04:23

This lecture introduces the fundamental concept of feedback control, a cornerstone of cybernetics, illustrating how systems maintain stability and achieve goals through self-regulation.

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.
