Doubly Semi-Implicit Variational Inference

Dmitry Molchanov, Valery Kharitonov, Artem Sobolev, Dmitry Vetrov

AISTATS 2019poster

We extend the existing framework of semi-implicit variational inference (SIVI) and introduce doubly semi-implicit variational inference (DSIVI), a way to perform variational inference and learning when both the approximate posterior and the prior distribution are semi-implicit. In other words, DSIVI…

Importance Weighted Hierarchical Variational Inference

Artem Sobolev, Dmitry P Vetrov

NeurIPS 2019poster

Variational Inference is a powerful tool in the Bayesian modeling toolkit, however, its effectiveness is determined by the expressivity of the utilized variational distributions in terms of their ability to match the true posterior distribution. In turn, the expressivity of the variational family is…
