Feature Measurement Invariance Under Morphological Damage Heterogeneity: A Cross-Dataset Validation Framework for Information-Theoretic Bearing Fault Diagnosis

Vibration-based bearing fault diagnosis relies on features extracted from continuous sensor measurements; yet their reliability as diagnostic measurements degrades when damage morphology differs between training and deployment datasets. This article frames domain transfer as a measurement invariance problem: a feature...
