Dirichlet Graph Auto-Encoders

This is a Pytorch implementation of the Dirchlet Graph Variational Auto-Encoder model (DGVAE), NIPS 2020.

DGVAE is an end-to-end trainable neural network model for unsupervised learning, generation and clustering on graphs. This code is more related to graph generation, as described in our paper.

DGVAE is based on Variational Graph Auto-Encoder (VGAE):
