Variational Free Energy: Difference between revisions

'''Variational free energy''' is the central quantity in variational Bayesian inference — and, by extension, in the Free Energy Principle's account of biological self-organization. It is a measure of the discrepancy between an approximate probability distribution and the true posterior distribution over hidden variables, given observed data. Minimizing variational free energy produces the best tractable approximation to exact Bayesian inference, while simultaneously placing a lower bound... |
