Rolling bearing fault diagnosis under variable speed and noisy conditions using multidomain ConvNeXt features and random forest decisions

A staged TL-ConvNeXt-RF framework in which 1024-point vibration windows are represented by spatially aligned time-domain, fast Fourier transform amplitude, and Hilbert–Huang marginal-spectrum channels supports RF ensemble decisions as a useful noise-stability mechanism for multidomain ConvNeXt features under the evalua...
