A recurrent neural network approach for remaining useful life prediction utilizing a novel trend features construction method

no code implementations10 Dec 2021 Sen Zhao, Yong Zhang, Shang Wang, Beitong Zhou, Cheng Cheng

Data-driven methods for remaining useful life (RUL) prediction normally learn features from a fixed window size of a priori of degradation, which may lead to less accurate prediction results on different datasets because of the variance of local features.

PowerSGD: Powered Stochastic Gradient Descent Methods for Accelerated Non-Convex Optimization

no code implementations25 Sep 2019 Jun Liu, Beitong Zhou, Weigao Sun, Ruijuan Chen, Claire J. Tomlin, Ye Yuan

In this paper, we propose a novel technique for improving the stochastic gradient descent (SGD) method to train deep networks, which we term \emph{PowerSGD}.

A Novel GAN-based Fault Diagnosis Approach for Imbalanced Industrial Time Series

no code implementations1 Apr 2019 Wenqian Jiang, Cheng Cheng, Beitong Zhou, Guijun Ma, Ye Yuan

This paper proposes a novel fault diagnosis approach based on generative adversarial networks (GAN) for imbalanced industrial time series where normal samples are much larger than failure cases.

Wasserstein Distance based Deep Adversarial Transfer Learning for Intelligent Fault Diagnosis

no code implementations2 Mar 2019 Cheng Cheng, Beitong Zhou, Guijun Ma, Dongrui Wu, Ye Yuan

However, for diverse working conditions in the industry, deep learning suffers two difficulties: one is that the well-defined (source domain) and new (target domain) datasets are with different feature distributions; another one is the fact that insufficient or no labelled data in target domain significantly reduce the accuracy of fault diagnosis.
