A smart structural health diagnosis system for few-shot bearing fault detection using Mamba and edge-attention GNN

Bearings are core load-bearing components of rotating machinery, and local structural damage will easily cause severe faults and even catastrophic industrial equipment shutdowns. Current intelligent bearing diagnosis methods face three major bottlenecks in actual factory scenarios: severely limited labeled fault sample...
