Document Type and Number:
WIPO Patent Application WO/2019/181675
Kind Code:
A1
Abstract:
An objective of the present invention is to provide a classifier correction device, classifier correction method, program, etc., for enabling efficiently improving precision even in a classifier for carrying out a classification wherein biases exist in data volumes for each class. A classifier correction device according to a mode of the present invention comprises: a set selection part wherein, with respect to a classifier for classifying which of a plurality of classes a given vector belongs to on the basis of a plurality of reference vectors which respectively belong to the plurality of classes, the set selection part selects a set of learning vectors which belong to respectively different classes from among a plurality of learning vectors for the classifier which respectively belong to the plurality of classes and for which there is at least one of the plurality of learning vectors belonging to each class; and a correction part for carrying out a correction process for correcting, for each of the learning vectors included in the set, with the learning vectors as a reference, the reference vectors which are identified on the basis of the learning vectors.
