適応型モニタリングシステムにおけるコンセプトドリフト検出に向けた初期実験

抄録

We propose a monitoring system based on concepts composed of a number of features as a monitoring target. Self-Organizing-Maps (SOM) is utilized to obtain concepts and to classify a new event into one of the concept. To make the system sustainable, the system has to deal with concept drift such as change of a concept and appearance of a new concept over time. In this work, we tried to validate use of cluster assignment error as a detection criterion of concept drift and the alogrism to detect concept drfit.
