摘要：The task of this paper is to detect the structural changes in machine status, such that those abnormal and unexpected running behaviors for the considered machine can be found and localized during its successive operations. To accomplish a task of this kind, we propose a new method by integration of the autoregressive integrated moving average model (ARIMA) and one-class SVM. The ARIMA model has been introduced and adopted for this problem in a previous work, where parameters in the model are somewhat difficult to estimate. In this paper, we propose to use the one-class SVM for the ARIMA model identification. This replacement can take advantage of machine learning method to learn a more reliable and more accurate model; meanwhile, it uses an unsupervised manner to detect the potential change which makes it different from other existing integrated methods that require massive samples to accomplish a prior model training. We conducted experiments based on an experimental setup. Results along with comparisons with representative methods demonstrated the effectiveness and propriety of the proposed method in real engineering applications.
