| Abstract(in English) | We have been proposed a pre-fault detection system based on Gaussian Processes (GP). The advantage of GP based pre-fault detection is that it can estimate not only the estimated output but also the standard deviation of the output. However, the anomaly can sometimes be detected as short-term phenomena and sometimes as long-term tendency. If we simply apply GP to high-dimensional vectors sampled within wide temporal window, the method requires huge number of training samples to keep the sensitivity and the accuracy. This is because GP is an example based non-linear regression method. For solving this problem, we introduce a multi-resolutional analysis along temporal axis that produces multiple signals with different smoothing windows from a single signal. By applying our GP based pre-fault detection method to these multi-scale signals, we can realize a versatile and reliable pre-fault detection system. |
