Abstract: In a case where data including an input, first operation executed onto the input, and a first result obtained by the first operation is defined as validation data and data used in an evaluation target period is defined as test data, a density relation estimating unit 81 estimates a relationship between a density of a pair including an input of the validation data and the first operation onto the input and a density of the pair including an input of the test data and second operation to be executed onto the input. An expected result estimating unit 82 estimates a second result expected to be obtained by executing the second operation onto the input of the test data on the basis of the first result included in the validation data and the estimated relationship.
