Fault feature extraction method based on local mean decomposition Shannon entropy and improved kernel principal component analysis model

To effectively extract the typical features of the bearing, a new method that related the local mean decomposition Shannon entropy and improved kernel principal component analysis model was proposed. First, the features are extracted by time–frequency domain method, local mean decomposition, and usi...
