WebDefinition 1: Energy Story. An energy story is a narrative describing a process or event. The critical elements of this narrative are: Identifying at least two states (e.g. start and end) in the process. Identifying and listing the matter in the system and its state at the start and end of the process. WebThe free energy principle is a mathematical principle in biophysics and cognitive science (especially Bayesian approaches to brain function, but also some approaches to artificial intelligence ). It describes a formal account of the representational capacities of physical systems: that is, why things that exist look as if they track properties ...
