TL;DR通过Markov chain Monte Carlo（MCMC）与varational inference（VI）相结合，并引入variational contrastive divergence（VCD）作为新的divergence，可以更好的预测潜在变量模型。
Abstract
We develop a method to combine markov chain monte carlo (MCMC) and variational inference (VI), leveraging the advantages of both inference approaches. Specifically, we improve the variational distribution by runn
