APPARATUS AND METHOD FOR CLASSIFYING TIME-SERIES DATA AND TIME-SERIES DATA PROCESSING APPARATUS

摘要

A time-series data classifying apparatus may include a first database, a peak feature extracting unit, a second database, a data input unit, and a predicting unit. The first database stores a plurality of cases each including time-series data a classification label. The peak feature extracting unit may, for each of the cases, calculate intersection points of time-series data expanded in a coordinate system and each reference line, detect a peak point in each of sections formed between two intersection points being adjacent to generate a peak feature sequence that contains a sequence of detected peak points. The second database may store each peak feature sequence in association with a classification label of each of the cases. The data input unit may input target time-series data. The predicting unit may predict a classification label to be assigned to the target time-series data based on the second database.
