| Abstract(in English) | In this paper, we deal with the degradation detection problem. for telecommunication network gateways. The time series to be monitored is non-stationary but almost periodic (pseudo-periodic). The authors propose a technique called "optimization of partition model" which generates local stationary models for a pseudo-periodic time series. The optimization is based on the minimal AIC principle. The technique called SPRT is also applied to make efficient decisions. By experiments using real traffic data, the proposed method of optimization and that of incremental update are evaluated in comparison with the conventional method. The result shows the proposed method is effective and makes more precises decision than the conventional one. |
