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.","summary":"2006 paper by Friston, Kilner and Harrison establishing the variational free energy principle for brain function.","claim_ids":["c1","c2","c3"],"found_by":"grok/grok-4.3","extra":{},"accessed_at":"2026-07-07T20:27:04.534Z","link_status":"ok","quote_status":"unverified","prev":"genesis","hash":"5b346c0f9b24cae70b62d0837d93893e43b9ddf1fd37aa8ca0b4bd986ae6f33a"}]}
