An interpretable cross-domain bearing fault diagnosis method based on domain-aware and informed-guided domain adaptation

Accurate cross-domain fault diagnosis of bearings is critical to the collaborative and intelligent operation of mechanical systems. However, structural differences between devices and variations in operating parameter settings cause the collected sensor data to exhibit notable nonlinear feature distribution shifts. Thi...
