PT-LGBM: An End-to-End Interpretable Cross-Domain Model for High-Speed Train Bearing Fault Diagnosis Under Class Imbalance

2026-08-31

Abstract excerpt

<title>Abstract</title> <p>Generalizing the high diagnostic accuracy achieved under laboratory conditions to high-speed train bearings operating in real-world environments is critical. Existing methods remain limited in their ability to address fault-class imbalance, domain shift, and insufficient interpretability simultaneously, leaving the reliability of cross-domain diagnosis inadequately validated. This study...
