A Bearing Fault Diagnosis Method Based on Dual-Stream Hybrid-Domain Adaptation

A Bearing Fault Diagnosis Method Based on Dual-Stream Hybrid-Domain Adaptation

Bearing fault diagnosis under varying operating conditions faces challenges of domain shift and labeled data scarcity. This paper proposes a dual-stream hybrid-domain adaptation network (DS-HDA Net) that fuses CNN-extracted time-domain features with MLP-processed frequency-domain features for compre...
