What Is Free Energy Principle | Frenly Guru

The free energy principle, proposed by Karl Friston, is a mathematical principle that describes how the brain reduces surprise or uncertainty by making predictions based on internal models and updating those models based on sensory input, approximating an integration of Bayesian inference with active inference. This principle has been applied to fMRI brain imaging data as a theoretical framework, providing insights into brain function, perception, and action, and has connections to information theory and machine learning.
