[Abstract]

A fundamental task in various fields of science is to find underlying causal relations and make use of them. Causal relations can be seen if interventions are properly applied; however, it is often difficult to conduct. Hence, it is necessary to discover causal relations by analyzing statistical properties of purely observational data, which is known as causal discovery; however, it is often impossible owing to the non-identifiability. In this talk, I introduce the Gaussian and Poisson directed acyclic graphical (DAG) models for the causal discovery. In addition, I provide how these models can be identifiable without any experiments or interventions, and how the model can be learned in finite sample settings.
