Abstract

See full text

An information processing device 1X mainly includes first and sorting means 14X and 15X, a feature value selection means 16X, and a learning means 17X. The first sorting means 14X performs a first sorting for sorting observation feature values of a target person based on attribute and/or environment of the target person. The second sorting means 15X performs a second sorting for sorting the observed feature values based on an observation target of the observed feature values and/or an activity state of the target person. The feature value selection means 16X selects stress estimation feature values for stress estimation from the observed feature values sorted based on the first sorting and the second sorting. The learning means 17X trains a stress estimation model based on the stress estimation feature values and corresponding correct stress values for each cluster of the observed feature values sorted by the first sorting.
