Information Processing Apparatus, And Information Processing Method

Abstract: This information processing device is provided with: a distance matrix calculation unit (104) which generates, from a dataset including a plurality of samples, a similarity degree matrix provided with a plurality of columns and a plurality of rows that are arranged according to the order in which the plurality of samples are arranged, wherein a field identified by one of the plurality of columns and one of the plurality of rows stores the degree of similarity between the samples corresponding to that column and that row; a sequence adjustment unit (105) which refers to label information indicating the result of labeling each of the plurality of samples using a plurality of labels each associated with a plurality of classes, and generates an adjusted similarity degree matrix by adjusting the sequences of the original similarity degree matrix in such a way that the plurality of samples are arranged for each of the plurality of classes associated with a target label specified from among the plurality of labels; a visualization unit (106) which generates an evaluation screen image showing each field of the adjusted similarity degree matrix in such a manner that the field has a brightness corresponding to the degree of similarity stored in the field; and a display unit (107) which displays the evaluation screen image.
