Active inference assumes that perception and action minimise variational free energy, where actions are selected to minimise the free energy expected in the future. This assumption generalises risk-sensitive control and expected utility theory to include epistemic value; namely, the value (or salience) of information inherent in resolving uncertainty about the causes of ambiguous cues or…
