Utilizing Autoregressive Networks for Full Lifecycle Data Generation of Rolling Bearings for RUL Prediction

no code implementations2 Jan 2024 Junliang Wang, Qinghua Zhang, Guanhua Zhu, Guoxi Sun

Our findings demonstrate that the CVGAN model, in terms of both MMD and FID metrics, outperforms many advanced methods in both autoregressive and non-autoregressive generation modes.

Utilizing Multiple Inputs Autoregressive Models for Bearing Remaining Useful Life Prediction

no code implementations26 Nov 2023 Junliang Wang, Qinghua Zhang, Guanhua Zhu, Guoxi Sun

Accurate prediction of the Remaining Useful Life (RUL) of rolling bearings is crucial in industrial production, yet existing models often struggle with limited generalization capabilities due to their inability to fully process all vibration signal patterns.

GBG++: A Fast and Stable Granular Ball Generation Method for Classification

no code implementations29 May 2023 Qin Xie, Qinghua Zhang, Shuyin Xia, Fan Zhao, Chengying Wu, Guoyin Wang, Weiping Ding

Second, considering the influence of the sample size within the GB on the GB's quality, based on the GBG++ method, an improved GB-based $k$-nearest neighbors algorithm (GB$k$NN++) is presented, which can reduce misclassification at the class boundary.
