摘要

Feature extraction apparatusA data acquisition section (110) for acquiring time series data as input time series data (D1) andHaving multiple digital filtersEach digital filter is applied to the input time series data (D1) acquired by the data acquisition sectionA plurality of filter application units (120) for outputting filter response time series data (D5) which are time series data including time series features or frequency features after application to digital filtersMultiple filter response time series data (D5) output by a plurality of filter applicationsThe feature quantity is extracted every filter response time series dataA feature extractor (130) which outputs the extracted feature quantity as feature quantity data (D2) andWas provided.
