WebOct 23, 2024 · Minimizing free energy provides a way of achieving this. Friston believes the free energy principle lies at the heart of all systems of life. The “free energy principle” gives a way of unifying all areas of research - from AI to biology to economics - behind the idea of “minimizing free energy.” Webof the minimization of variational free energy (Friston et al. 2006; Friston 2010; Friston et al. 2024). The free energy principle (hereafter simply FEP) was born. In the following years, FEP was expanded beyond brains and was proposed, first, as a general principle for the self-organization of biological systems (Friston 2013; Ramstead et al ...

WebBox 1. The free-energy principle Free-energy is a function of a recognition density and sensory input. It comprises two terms; the energy expected under this density and its entropy. The energy is simply the surprise about the joint occurrence of sensory input y and its causes #. The free-energy depends on two WebJul 1, 2009 · Free-energy is an information theory quantity that bounds the evidence for a model of data 1, 2, 3. Here, the data are sensory inputs and the model is encoded by the brain. More precisely, free-energy is greater than the negative log-evidence or ‘surprise’ in sensory data, given a model of how they were generated.
