Bearing-Fault Classification via Physics-Guided Representation Alignment and Group Ordinal Labeling

Substantial progress has been made in bearing-fault classification under same-condition settings, yet cross-condition diagnosis remains affected by three coupled issues: speed-induced temporal-scale perturbation, insufficient use of structured label information, and domain shift across operating con...
