Title:
INFORMATION PROCESSING DEVICE, INFORMATION PROCESSING METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2014/136316
Kind Code:
A1
Abstract:
An information processing device (10) which performs semi-supervised learning is provided with: a dictionary input unit (110) for acquiring a dictionary, i.e. a parameter group used by an identification device; a boundary determination unit (120) which obtains an identification boundary for the dictionary on the basis of the dictionary, supervised data (172), and labelled unsupervised data (174); a labelling unit (130) which labels the unsupervised data (174) in accordance with the identification boundary; a loss calculation unit (140) which calculates the sum total of supervised-data (172) loss calculated in accordance with the labels assigned in advance and the labels based on the identification boundary, and unsupervised-data (174) loss calculated such that further from the identification boundary the smaller the loss; a dictionary update unit (150) which updates the dictionary such that the sum-total loss is reduced; and a dictionary output unit (160) which outputs the updated dictionary.
