The diagnosis of compound faults in bearings is a challenging issue in real industrial scenarios, as these faults have a significant impact on production and safety. Moreover, the data related to these compound faults are difficult to collect and label, making data-driven fault diagnosis methods inapplicable. To addr...

Field vibration monitoring of EMU traction motor bearings is commonly constrained by weak or relative labels, fluctuations in operating conditions, and limited abnormal samples. Under these conditions, learning a normal boundary from a single bearing position may be unstable, and isolated score spikes may lead to unrel...

Switch machines are critical components in rail transit signal systems, ensuring the safe, efficient, and smooth operation of trains. However, due to the harsh working conditions, they are the most failure-prone among all ground signal devices. Existing studies mainly pursue higher diagnostic accuracy via specialized m...
