Operational status classification device

Abstract

A to-be-classified data generating unit generating to-be-classified data from pieces of sensor data collected from an apparatus; a division candidate selecting unit selecting, as division candidates, candidates of boundary lines used to divide a value range of the to-be-classified data generated by the to-be-classified data generating unit; and a connection density calculating unit calculating, for each division candidate selected by the division candidate selecting unit, a connection density representing closeness of collection timings between pieces of the to-be-classified data divided by each division candidate are provided. Further, a classifying unit extracting division candidates to be used for classifying the operational statuses from among the division candidates using the connection density calculated by the connection density calculating unit, and classifying the to-be-classified data into respective operational statuses by dividing the value range of the to-be-classified data using the extracted division candidates is provided.
