DATA PROCESSING DEVICE, DATA PROCESSING METHOD, AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To detect a feature by generating a feature vector from time-series data exhibiting a phenomenon in which the occurrence time is temporally irregular.SOLUTION: The data processing device includes: a series acquisition unit for acquiring a data series having a plurality of arranged data; a dividing unit for dividing the data series into a plurality of partial data series; a pattern extraction unit for extracting a plurality of patterns of one or more data appearing in at least one of the plurality of partial data series; and a generation unit for generating a feature vector having an element value for each of the plurality of partial data series. Here, the element value changes on the basis of whether each series includes each of the plurality of patterns. A data processing method and a program are also provided.SELECTED DRAWING: Figure 1
