# How particular is the physics of the Free Energy Principle?

The Free Energy Principle (FEP) states that any dynamical system can be interpreted as performing Bayesian inference upon its surrounding environment. Although the FEP applies in theory to a wide variety of systems, there has been almost no direct exploration of the principle in concrete systems. In this paper, we examine in depth the assumptions required to derive the FEP in the simplest possible set of systems – weakly-coupled non-equilibrium linear stochastic systems. Specifically, we… Expand

A free energy principle for a particular physics

- Biology

The main contribution is to examine the implications of Markov blankets for self-organisation to nonequilibrium steady-state and recover an information geometry and accompanying free energy principle that allows one to interpret the internal states of something as representing or making inferences about its external states.

Recognition Dynamics in the Brain under the Free Energy Principle

This work formulate the computational processes of perception in the framework of the principle of least action by postulating the theoretical action as a time integral of the variational free energy in the neurosciences and derives neural recognition dynamics (RD), which by construction reduces to the Bayesian filtering of external states from noisy sensory inputs.

Markov blankets, information geometry and stochastic thermodynamics

There is a natural Bayesian mechanics for any system that possesses a Markov blanket, which means that there is an explicit link between the inference performed by internal states and their energetics—as characterized by their stochastic thermodynamics. Expand

It is shown how the ReML objective function can be adjusted to provide an approximation to the log-evidence for a particular model, which means ReML can be used for model selection, specifically to select or compare models with different covariance components. Expand

The FEP, as it stands formulated today, is profoundly incompatible with the theories of autopoiesis and enaction, and a series of misreadings and misinterpretations of key enactive concepts are identified. Expand
