Active Invariant Causal Prediction: Experiment Selection through Stability Juan L. Gamella Christina Heinze-Deml Seminar for Statistics Seminar for Statistics ETH Zurich

A fundamental difficulty of causal learning is that causal models can generally not be fully identified based on observational data only. Interventional data, that is, data originating from different experimental environments, improves identifiability. However, the improvement depends critically on the target and nature of the interventions carried out in each experiment. Since in real applications experiments tend to be costly, there is a need to perform the right interventions such that as few as possible are required. In this work we propose a new active learning (i.e.
