WebDec 26, 2024 · It is designed to solve the few-shot fault diagnosis of the cross-component problem in rotating machines: the model is trained by one component with sufficient data and tested in another component with little data. First, a multiscale wavelet convolution module is designed to extract abundant features. Second, a metric meta-learner module … WebSep 9, 2024 · In this article, we propose a new few-shot learning method named dual graph neural network (DGNNet) with residual blocks to address fault diagnosis problems with limited data. First, the residual module learns the feature of samples with image data transferred from original signals.
