The Free-Energy Principle

Self-organizing, self-evidencing systems maintain themselves at a non-equilibrium-steady state, and thereby implicitly performing variational Bayesian inference.

$\pi ,o,s=\text{arg min }F(\tilde{o},\pi |s)$ For Perception (Variational Free Energy):

Can be also arranged as: $\mathcal{F}(D,\theta )=\underset{\text{Accuracy}}{\underbrace{{\mathbb{E}}_{q(H|D;\theta )}[\ln p(D|H)]}}+\underset{\text{Complexity}}{\underbrace{D_{KL}[q(H|D;\theta )\Vert p(H)]}}$ For Active Inference see:
