Exploring the Concept of Free Energy and Bayesian Mechanics

The variational free energy measures the evidence for a generative model of the causes of data, allowing the exploration of Bayesian mechanics in performing inference and interpreting the dynamics of existence. This concept suggests that entities gather evidence for their own existence and possess a generative model of their external environment. Although aesthetically appealing and aligning with established physics theories, the practical application lies in the ability to build and simulate systems based on the principle of least action and gradient descent using the variational free energy.
