It formulates a variational free energy principle that unifies perception, action and learning in the brain. The core claim is that biological systems, including brains, minimise free energy. Free energy here is a bound on surprise in exchanges with the environment.\\n\\nThe paper starts from Helmholtz's ideas on unconscious inference. It recasts them in statistical physics terms. Brains use hierarchical generative models to infer causes of sensory data. Minimising free energy drives both updating internal models (perception) and changing the world through movement (action).\\n\\n## Core results and exact passages\\n\\nThe abstract states: \\\"By formulating Helmholtz’s ideas about perception, in terms of modern-day theories, one arrives at a model of perceptual inference and learning that can explain a remarkable range of neurobiological facts.\\\" It continues: \\\"In this paper, we show these perceptual processes are just one aspect of emergent behaviours of systems that conform to a free energy principle. The free energy considered here measures the difference between the probability distribution of environmental quantities that act on the system and an arbitrary distribution encoded by its configuration. The system can minimise free energy by changing its configuration to affect the way it samples the environment or change the distribution it encodes. These changes correspond to action and perception respectively.\\\"\\n\\nLater it says: \\\"The purpose of this paper is to suggest that inference is just one emergent aspect of free energy minimisation and that a free energy principle for the brain can explain the intimate relationship between perception and action.\\\"\\n\\nThe work derives this from selectioni","tokens_in":26565,"tokens_out":2453,"cost":0,"prev":"genesis","hash":"f1bd50fb066d735962e184f998f642747024eae31f78c47bcef134a9870a125a"},{"ts":"2026-07-07T21:30:36.705Z","model":"scorer","action":"score","prompt":"","input":"paper-friston-k-j-kilner-j-and-harrison-l-2006-a-free-energy-principle-for-the-brain","response":"[]","tokens_in":0,"tokens_out":0,"cost":0,"prev":"f1bd50fb066d735962e184f998f642747024eae31f78c47bcef134a9870a125a","hash":"0704b8d1cc7c9c25ca856a6d480d10a5d922cabd908213dfa2678e1ae74ee092"}]}
