WebApr 5, 2024 · A sliding window alarm method is proposed to detect the fault occurrence time (FOT), which can offer an accurate healthy stage rather than human-defined methods. Then, the STMSGCN is proposed to predict the RUL of bearings, which solves the over-smoothing problem of the deep graph neural network (GNN) model. Webtions. While results were promising, overly smooth in-ferences prevented architectures with more than 2 layers from improving performance like they had in the image processing domain. Several works have since looked at solving this over-smoothing problem. Xu et al.[7] introduced Jumping Knowledge Networks (JKNet) which aggregated out-
