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.
