A free-energy principle for representation learning [PDF]
Machine Learning: Science and Technology, 2021 Abstract This paper employs a formal connection of machine learning with thermodynamics to characterize the quality of learned representations for transfer learning. We discuss how information-theoretic functionals such as rate, distortion and classification loss of a model lie on a convex, so-called, equilibrium surface.

A free energy principle for the brain [PDF]
Journal of Physiology-Paris, 2006 By formulating Helmholtz's ideas about perception, in terms of modern-day theories, one arrives at a model of perceptual inference and learning that can explain a remarkable range of neurobiological facts: using constructs from statistical physics, the problems of inferring the causes of sensory input and learning the causal structure of their ...

Affect-Logic, Embodiment, Synergetics, and the Free Energy Principle: New Approaches to the Understanding and Treatment of Schizophrenia. [PDF]
Entropy (Basel), 2021 This theoretical paper explores the affect-logic approach to schizophrenia in light of the general complexity theories of cognition: embodied cognition, Haken’s synergetics, and Friston’s free energy principle.

Application of the Free Energy Principle to Estimation and Control [PDF]
IEEE Transactions on Signal Processing, 2021 Based on a generative model (GM) and beliefs over hidden states, the free energy principle (FEP) enables an agent to sense and act by minimizing a free energy bound on Bayesian surprise. Inclusion of prior beliefs in the GM about desired states leads to active inference (ActInf).

Non-equilibrium Thermodynamics and the Free Energy Principle in Biology [PDF]
, 2021 According to the free energy principle, life is an “inevitable and emergent property of any (ergodic) random dynamical system at non-equilibrium steady state that possesses a Markov blanket” (Friston 2013).

Natural language syntax complies with the free-energy principle. [PDF]
Synthese, 2021 Natural language syntax yields an unbounded array of hierarchically structured expressions. We claim that these are used in the service of active inference in accord with the free-energy principle (FEP). While conceptual advances alongside modelling and simulation work have attempted to connect speech segmentation and linguistic communication with the ...

Reinforcement learning or active inference? [PDF]
, 2009 This paper questions the need for reinforcement learning or control theory when optimising behaviour. We show that it is fairly simple to teach an agent complicated and adaptive behaviours using a free-energy formulation of perception.

Philosophies, 2021 A weak version of the life-mind continuity thesis entails that every living system also has a basic mind (with a non-representational form of intentionality).
