Query: Fixed-Form Variational Posterior Approximation through Stochastic Linear
  Regression   We propose a general algorithm for approximating nonstandard Bayesian
posterior distributions. The algorithm minimizes the Kullback-Leibler
divergence of an approximating distribution to the intractable posterior
distribution. Our method can be used to approximate any posterior distribution,
provided that it is given in closed form up to the proportionality constant.
The approximation can be any distribution in the exponential family or any
mixture of such distributions, which means that it can be made arbitrarily
precise. Several examples illustrate the speed and accuracy of our
approximation method in practice.
