Title:
DATA CLASSIFICATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/092997
Kind Code:
A1
Abstract:
An objective of the present invention is to provide a data classification device and malfunction diagnostic system capable of reducing false detections. For this purpose, a data classification device according to the present invention comprises: a data classification part 30 for classifying operation data into a plurality of categories; and a classification result database 40 for managing the output of the data classification part. The data classification part 30 preferentially selects, as candidate categories, the categories having lower generation numbers, which represent the order in which the categories have been generated, and determines the categories of the operating data accordingly.
