Cognitive fatigue from schema rigidity and entropy externalization: a free energy principle perspective [PDF]

open access: yesFrontiers in Psychology
Cognitive fatigue is typically described as a psychobiological state that arises from intensive and/or prolonged cognitive performance and is experienced as a subjective feeling of exhaustion and lack of energy.

The Markov blankets of life: autonomy, active inference and the free energy principle [PDF]

open access: yesJ R Soc Interface, 2018
This work addresses the autonomous organization of biological systems. It does so by considering the boundaries of biological systems, from individual cells to Home sapiens, in terms of the presence of Markov blankets under the active inference scheme—a ...

The Free Energy Principle: Good Science and Questionable Philosophy in a Grand Unifying Theory [PDF]

open access: yesEntropy, 2021
The Free Energy Principle (FEP) is currently one of the most promising frameworks with which to address a unified explanation of life-related phenomena.

A free-energy principle for representation learning [PDF]

open access: yesMachine 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]

open access: yesJournal 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 ...

Application of the Free Energy Principle to Estimation and Control [PDF]

open access: yesIEEE 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).

The free energy principle induces neuromorphic development

open access: yesNeuromorphic Computing and Engineering, 2022
Abstract We show how any finite physical system with morphological, i.e. three-dimensional embedding or shape, degrees of freedom and locally limited free energy will, under the constraints of the free energy principle, evolve over time towards a neuromorphic morphology that supports hierarchical computations in which each ‘level’ of the

Reinforced Imitation Learning by Free Energy Principle

open access: yesCoRR, 2021
Reinforcement Learning (RL) requires a large amount of exploration especially in sparse-reward settings. Imitation Learning (IL) can learn from expert demonstrations without exploration, but it never exceeds the expert's performance and is also vulnerable to distributional shift between demonstration and execution.

Renormalization Group Flow and Thermodynamics of Conformal Field Theories [PDF]

open access: yes, 1999
We discuss the free-energy density of bosonic and fermionic theories possessing strongly coupled critical points in D=3. We construct a stationary renormalization group trajectory which interpolates between the free massless theory of N scalars and a ...
