Abstract
A system calculates an inter-distribution distance between target data and base data for each of one or more second periods in an entire period between an end time of a first period and a relearning timing of a learning model. For each second period, the target data is data for the second period in the entire data that is data for the entire period. The base data is data for the first period and is data related to creation of the learning model. The system specifies, as a variation point, a time in accordance with the second period during which the calculated inter-distribution distance is greater than or equal to a threshold. The system determines and outputs one or more training data candidates from a part or all of the entire data based on the one or more variation points for relearning of the learning model.
