Document Type and Number:
WIPO Patent Application WO/2020/004049
Kind Code:
A1
Abstract:
The present disclosure relates to an information processing device, an information processing method, and a program that make it possible to facilitate improvement in a learning dataset. In the present invention, a prediction analysis unit calculates evaluation values for an evaluation dataset, which is used to evaluate a prediction model, with a prescribed number of data samples in a learning dataset, which is used to learn the prediction model, and an advice generation unit generates presentation information for presenting advice regarding at least either of the data samples in the learning dataset and features thereof on the basis of evaluation values for all the data samples in the learning dataset and gradients thereof. The technology according to the present disclosure is applicable, for example, to prediction of a contract price for a secondhand condominium.
