- 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.
- Framework for non-equilibrium free energies; mentioned as future direction to generalise results
- Theoretical framework governing far-from-equilibrium self-organizing systems; underpins model of action formation.
- Limit of large system size; used in scaling arguments
- Free energy expected under future outcomes; guides policy selection via epistemic and extrinsic value.
- Scalar potential in Helmholtz decomposition whose exponential form gives the ergodic density of dynamical systems.
- The dead inert state where all energy differences are equalized; organisms avoid this by metabolism.
- Minimizing expected free energy for planning, decision-making, and action selection.
