A Fault Feature Extraction Method of Rolling Bearings Based on Optimized VMD and UMAP

A Fault Feature Extraction Method of Rolling Bearings Based on Optimized VMD and UMAP

In view of the problem of difficulties in extracting low-dimensional sensitive features from rolling bearing vibration signals, a rolling bearing fault feature extraction method based on logistic regression optimization variation mode decomposition(VMD) and uniform manifold approximation and project...
