Scalable Graph Convolutional Variational Autoencoders

2021 IEEE 15th International Symposium on Applied Computational Intelligence and Informatics (SACI), 2021
Autoencoders are widely used for self-supervised representation learning. Variational autoencoders (VAEs), a special type of autoencoders, are proven to be effective in estimating the underlying probability distribution of the training data. Even though VAEs are well explored in many application domains, their utilization for graph-structured data is ...

VACA: Designing Variational Graph Autoencoders for Causal Queries

Proceedings of the AAAI Conference on Artificial Intelligence, 2022
In this paper, we introduce VACA, a novel class of variational graph autoencoders for causal inference in the absence of hidden confounders, when only observational data and the causal graph are available. Without making any parametric assumptions, VACA mimics the necessary properties of a Structural Causal Model (SCM) to provide a flexible and ...
