Abstract: A query specification unit 81 specifies a query as a combination of a variable, on which an intervention operation is performed for a causal relation, and a value of the variable. An intervention data generating unit 82 generates intervention data including a value of a target variable, acquired with an intervention operation based on the query, and the query. A causal relation updating unit 83 updates the causal relation using the generated intervention data. On this occasion, the query specification unit 81 specifies a query that minimizes an expected loss by updating from among queries specified based on the expected loss representing an estimation error of the target variable by the query.

Abstract: In an optimization device 80, an explanatory variable used for explanation of a prediction target becomes an instrumental variable for optimization, and the optimization is performed on the basis of a prediction of the prediction target. A candidate set determination unit 81 determines a set of candidates for a predicted instrumental variable. For instrumental variables included in the set, a margin determination unit 82 determines a margin including an estimation error, which is an error due to the prediction, with a designated probability. A robust optimization unit 83 performs robust optimization related to the instrumental variables by using the determined margin.

Abstract: A first reception unit 81 receives, as an input, a graph including: a plurality of nodes representing experimental operations; a plurality of nodes representing results of the operations; and edges representing cause-and-effect relationships between the experimental operations and the operation results. A second reception unit 82 receives, as an input, either information indicating the degree of cause-and-effect relationship between each experimental operation and each operation result or past experimental results from which the strength of each cause-and-effect relationship can be estimated. On the basis of the input received by the first reception unit 81 and the information received by the second reception unit 82, an output unit 83 outputs the order in which a plurality of experimental operations are to be performed.
