Free energy principle[edit]    - 2020

The Free energy principle provides an explanation for embodied perception in neuroscience and tries to explain how biological systems maintain order by restricting themselves to a limited number of states or beliefs about hidden states in their environment. A biological system performs active inference in sampling action outcomes to maximise the evidence for its model of the world:

The notion that self-organising biological systems – like a cell or brain – can be understood as minimising variational free energy is based upon Helmholtz’s observations on unconscious inference[25] and subsequent treatments in psychology [26] and machine learning.[24]
