To provide an information processor capable of further improving the determination accuracy of a model.SOLUTION: A model creation device 100 includes: a learning data acquisition part 101 for acquiring sensor output data as learning data; a feature amount calculation part 102 for calculating a feature amount from the learning data; a data division part 103 for dividing the learning data based on the calculated feature amount; and a model creation part 104 for creating a model using the learning data after division. Additionally the model creation device includes: a verification data acquisition part 105 for acquiring sensor output data as verification data; an evaluation part 106 for evaluating the verification data based on the feature amount of the verification data and the created model; and a data redivision part 107 for redividing the learning data based on the learning data and the verification data according to the result of the evaluation. The model creation part creates a model using the learning data after redivision when the redivision of learning data is performed.SELECTED DRAWING: Figure 1
