WebApr 16, 2024 · KL term KL[q(u_f,u_l) p(u_f,u_l)] would be analytically tractable for gaussian VI posteriors. It's been done in Non-Stationary Gaussian Process Regression with Hamiltonian Monte Carlo by Heinonen et al. 2015, but they use HMC for inference. The idea is now to try it with VI by starting from the lengthscale. This is the idea till now. WebLower panel: mean field free energy, with energy shifted by θln2 so that f(m = 0, θ) = 0.

WebThe free energy becomes f(m, h, θ) = f0 + 1 2am2 + 1 4bm4 − hm , and the mean field equation is bm3 + am − h = 0 . This is a cubic equation for m with real coefficients, and as such it can either have three real solutions or one real solution and two complex solutions related by complex conjugation.

WebThe mean-field theory is an example of approximate solution. Onsager’s theory of the Ising model is an example of an exact solution. While the mean-field theory often seems too crude, the exact solutions are too complicated. A peculiar feature of critical phenomena is that there is very little one can do to improve the mean-field theory ...
WebMay 11, 2024 · Mean-field theory approximates the effect of the environment on any given individual degree of freedom by a single, averaged effect, and thus reduces a many-body problem to an (effective) one-body problem.
