On the Generative Utility of Cyclic Conditionals

1 code implementation NeurIPS 2021 Chang Liu, Haoyue Tang, Tao Qin, Jintao Wang, Tie-Yan Liu

This is motivated by the observation that deep generative models, in addition to a likelihood model $p(x|z)$, often also use an inference model $q(z|x)$ for extracting representation, but they rely on a usually uninformative prior distribution $p(z)$ to define a joint distribution, which may render problems like posterior collapse and manifold mismatch.
