Reviews: Semi-Implicit Graph Variational Auto-Encoders

The paper "carefully designed the SIG-VAE model" and showed SOTA results. We judged that the contributions are significant, but reviewers raised the following concerns. SIG-VAE modeling (3-4) for graph analysis, giving strong empirical result (SOTA in link prediction, comparable in node classification, etc.) - Contribution in interpretability is not convincing. We strongly recommend the authors to revise the paper significantly. The biggest problem is in organization. The paper is written as if the main contribution is SIVI GVAE, which is straightforward as reviewers pointed out.
