Abstract: An information processing device includes processing circuitry configured to acquire a plurality of pieces of data, input the pieces of data to a model as input data, and in a case of obtaining output data output from the model, calculate an importance of each component of the input data with respect to the output data based on the input data and the output data, acquire a binding coefficient indicating a relevance among components of the input data, calculate a bound importance obtained by applying the binding coefficient to the importance, and create information indicating the bound importance of each input item.

Abstract: A computing device uses image data as an input, and estimates skeleton data by using a skeleton estimation model for estimating the skeleton data related to a skeleton of a person. The computing device then calculates weight values of respective articulations based on reliability of estimation results of the respective articulations, and computes a similarity between pieces of the skeleton data by using the calculated weight values of the respective articulations. The computing device then determines whether the similarity is equal to or larger than a predetermined threshold. If the similarity is equal to or larger than the predetermined threshold, the computing device determines that authentication has succeeded, and if the similarity is smaller than the predetermined threshold, the computing device determines that authentication has failed.

Abstract: An information processing device includes processing circuitry configured to obtain a plurality of sets of data related to a processing target, group relationships among the sets of data that are obtained, based on group information set in advance, calculate degrees of importance indicating strengths of cause-and-effect relationships among sets of data included in each group, and calculate, based on the degrees of importance, estimation values indicating the cause-and-effect relationships among sets of data.
