WebFeb 17, 2024 · The main idea of Rao-Blackwellization is to try and get rid of as many unneeded z's samples as possible. Assuming "mean field" we don’t really need all of the dimension of z in the calculations of the ELBO-derivative. So, we are going to “massage” the ELBO-derivative to remove unnecessary z’s. http://www.columbia.edu/~im2131/ps/rao-black.pdf

WebThis process is sometimes referred to as the Rao-Blackwellization of an estimator. Notice that putting E = Eθ and c = ψ(θ)in Theorem 8.1.1 implies that MSEθ(T) = Var θ(T)+(Eθ(T)−ψ(θ))2. (8.1.4) So the MSE of T can be decomposed as the sum of the variance of T plus the squared bias of T (this was also proved in Theorem 6.3.1).
