Non-parametric Ensemble Empirical Mode Decomposition for extracting weak features to identify bearing defects

Anil Kumar, Yaakoub Berrouche, Radosław Zimroz +5

A non-parametric complementary ensemble empirical mode decomposition (NPCEEMD) is proposed for identifying bearing defects using weak features. NPCEEMD is non-parametric because, u…
