| Abstract(in English) | Remaining Useful Life (RUL) is one of the most important assessment measures in reliability engineering. Although several widely-used public datasets have information on failure times, they do not have information on RUL. As a simple way, we can consider a linear degradation concerning the difference between the future failure time and the current time. However, since it is not always the case that such a linear degradation occurs, then we need to generate complex teacher labels incorporating the detection of changing points in the degradation states. In one of the previous studies, one proposed a failure prediction model that takes into account the degradation states and achieved some improvement in prediction accuracy. However, this model sometimes does not perform well, for example, it cannot be adapted to specific tagging methods. Therefore we propose Dual-task VAE incorporating Weibull distribution as a prediction model which does not depend on the tagging methods. |
