Title:
INFORMATION PROCESSING DEVICE, INFORMATION PROCESSING METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2019/008961
Kind Code:
A1
Abstract:
Provided is an information processing device (100) comprising: an input unit (102) for receiving an input of threshold values relating to similarity of feature values for each of a plurality of instances of data, said threshold values being a first threshold value for ascribing instances of data to the same group, and a second threshold value indicating a value lower than the first threshold value; and a grouping unit (104) for grouping the data using the similarity, first threshold value, and second threshold value. The grouping unit (104) places, in the same group, data having similarity with representative data that is higher than the first threshold value, and selects new representative data from the data having similarity to the existing representative data that is lower than the second threshold value.
