Project

Causal Inference using Deep Learning

The aim of the project is to investigate to what extent causal relationships in multivariate nonlinear dynamical systems can be derived from learned, deep networks. Estimating causal relations is vital in understanding the complex interactions in multivariate time series. Non-linear coupling of variables is one of the major challenges in accurate estimation of cause-effect relations. We propose to use deep autoregressive networks (DeepAR) in tandem with counterfactual analysis to infer nonlinear causal relations in multivariate time series. In this work, we extend the concept of Granger causality using probabilistic forecasting with DeepAR. We achieved promising results using our method in detecting nonlinear causal dependency in multivariate time series from synthetic as well as real-world datasets.
