Feature Extraction Strategy with Improved Permutation Entropy and Its Application in Fault Diagnosis of Bearings
Feature extraction is one of the most difficult aspects of mechanical fault diagnosis, and it is directly related to the accuracy of bearing fault diagnosis. In this study, improved permutation entropy (IPE) is defined as the feature for bearing fault diagnosis. In this method, ensemble empirical mo...
