Counterfactual domain generalization with adaptive source reweighting and causal disentanglement for bearing fault diagnosis

A multi-source domain generalization framework for bearing fault diagnosis based on class-conditional feature distance weighting and mechanism–style disentanglement that can effectively mitigate the influence of domain-related interference on fault identification and improve diagnostic stability in unseen domains is pr...

A Few-Shot Fault Diagnosis Algorithm for Rotating Machinery Based on Time-Frequency Dual-Stream Mamba and Joint Metric Learning

Experimental results show that the proposed few-shot fault diagnosis method consistently outperforms comparison methods under different rotational speeds, training sample scales, and 8-way 1-shot/5-shot tasks, validating its effectiveness and robustness for few-shot rotating machinery fault diagnosis.
