Causal relationship estimation device, causal relationship estimation method and causal relationship estimation program

摘要

The query specifying unit 81 identifies a query that is a combination of a variable in which an intervention operation is performed on a causal relationship and a value of the variable. The intervention data generation unit 82 generates intervention data including the value of the target variable acquired by the intervention operation based on the query and the query. The causal relationship updating unit 83 updates the causal relationship using the generated intervention data. At that time, the query specifying unit 81 identifies a query that minimizes the expected loss by updating among the queries specified based on the expected loss representing the estimation error of the target variable by the query.
