VACA: Designing Variational Graph Autoencoders for Causal Queries
2022
Conference Paper
plg
In this paper, we introduce VACA, a novel class of vari- ational graph autoencoders for causal inference in the ab- sence of hidden confounders, when only observational data and the causal graph are available. Without making any para- metric assumptions, VACA mimics the necessary properties of a Structural Causal Model (SCM) to provide a flexible and practical framework for approximating interventions (do- operator) and abduction-action-prediction steps. As a result, and as shown by our empirical results, VACA accurately ap- proximates the interventional and counterfactual distributions on diverse SCMs. Finally, we apply VACA to evaluate coun- terfactual fairness in fair classification problems, as well as to learn fair classifiers without compromising performance.
