Title:
FEATURE VALUE SELECTION METHOD, FEATURE VALUE SELECTION PROGRAM, MULTICLASS CLASSIFICATION METHOD, MULTICLASS CLASSIFICATION PROGRAM, FEATURE VALUE SELECTION DEVICE, MULTICLASS CLASSIFICATION DEVICE, AND FEATURE VALUE SET
Document Type and Number:
WIPO Patent Application WO/2021/161901
Kind Code:
A1
Abstract:
The present invention aims to provide: a multiclass classification method that selects a feature value and classifies a sample into one of a plurality of classes on the basis of the selected feature value; a multiclass classification program; a multiclass classification device; and a feature value selection method, a feature value selection device, and a feature value set that are used in this kind of multiclass classification. The present invention handles issues with multiclass classification that includes feature selection. Feature selection is a method whereby feature values required for latter-stage processes (i.e., multiclass classification, for this invention) are selected for adoption or rejection beforehand, from among a plurality of feature values in a sample. Multiclass classification is an issue of discrimination that determines which of a plurality of classes a given unknown sample belongs to.
