RIKEN Center for Advanced Intelligence Project Causal Inference Team

Team Leader: Shohei Shimizu (D.Eng.)

Research Summary

Shohei  Shimizu(D.Eng.)

Our group works on different topics related to causal inference. In particular, we develop theory, methods, algorithms, and software for estimating causal relations based on data that are obtained from sources other than randomized experiments, i.e., causal discovery.
