Sequential hierarchical cluster classification device, sequential hierarchical cluster classification method, and sequential hierarchical cluster classification program

摘要

PROBLEM TO BE SOLVED: To provide a sequential hierarchical cluster classification device, a classification method and a classification program for updating a cluster classification result in a short time when data is added. A sequential hierarchical cluster classification device (1) has a cluster analysis unit (12) for performing cluster classification on a plurality of data by hierarchical clustering, and after the cluster analysis unit (12) performs cluster classification on a plurality of data. In the case where new insertion data is added in, when the insertion data is not an outlier that satisfies the predetermined determination criterion, the update unit A that locally updates the cluster classification result for a plurality of data is provided.
