Free energy principle
Videos
The free energy principle is a mathematical principle of information physics. Its application to fMRI brain imaging data as a theoretical framework suggests that the brain reduces surprise or uncertai
Simulation of the results achieved from a selective attention task carried out by the Bayesian reformulation of the SAIM entitled PE-SAIM in multiple objects environment. The graphs show the time course of the activation for the FOA and the two template units in the Knowledge Network.

Variational Bayesian methods are a family of techniques for approximating intractable integrals arising in Bayesian inference and machine learning. They are typically used in complex statistical model

…upper bound). The principle is used in Bayesian approaches to brain function and some approaches to artificial intelligence; it is formally related to variational Bayesian methods. Karl Friston introduced it as an explanation for embodied perception-action loops in neuroscience. The free energy principle models the behaviour of…
