Feynman's Variational Free Energy

I'm a huge fan of Feynman's work. Sometimes even for fun I end up watching Feynman lectures just just keep me calm at night. He was trying to solve exactly the impossible marginalization problem that people would try to solve if they wanted to engage in exact sensing, exact sense making the exact statistics. So what he did was to dissolve that problem by converting this inference marginalization integration problem into an optimization problem. And he did it by creating this band on the quantity he wanted to optimize, namely the the log marginal likelihood, which is the variation for the energy. That's that they are all of the principle. It was a, you know, it's greatest debt
