Concepts (2)

concept
  • Perception
    about
    Equated with inference of past, present and future hidden states via minimization of variational free energy.
  • action
    about
    Changing configuration to sample environment differently; minimizes free energy.

Frameworks (1)

framework
  • Free Energy Principle
    about
    A foundational variational principle from statistical physics that formalizes how self-organizing systems maintain structural integrity and adapt to their environment by minimizing free energy—a mathematical bound on surprise or prediction error. Originally developed by Karl Friston, the framework unifies action, perception, and learning as processes of active inference, where systems both update internal models of the world and act upon it to reduce the divergence between predictions and observations.
