Abstract

The ‘free energy principle’ (FEP) has been suggested to provide a unified theory of the brain, integrating
data and theory relating to action, perception, and learning. The theory and implementation of the FEP
combines insights from Helmholtzian ‘perception as inference’, machine learning theory, and statistical
thermodynamics. Here, we provide a detailed mathematical evaluation of a suggested biologically plausible implementation of the FEP that has been widely used to develop the theory. Our objectives are (i) to describe within a single article the mathematical structure of this implementation of the FEP; (ii) provide a simple but complete agent-based model utilising the FEP and (iii) to disclose the assumption structure of this implementation of the FEP to help elucidate its significance for the brain sciences.
