Abstract
A class boundary detection apparatus () acquires target time-series data (). The class boundary detection apparatus () extracts a plurality of pieces of extracted time-series data from the target time-series data (), and calculates a similarity between each piece of extracted time-series data and reference time-series data (). The reference time-series data () is time-series data representing a class boundary, and has a head portion of time-series data belonging to a subsequent class indicated by the class boundary after a tail portion of time-series data belonging to a preceding class indicated by the class boundary. The class boundary detection apparatus () detects a class boundary represented by the reference time-series data () from extracted time-series data having the calculated similarity equal to or more than a threshold.
