“…In reference [25], Li et al presented a semisupervised diagnosis method based on a distance-preserving self-organizing map (SS-DPSOM) to identify 4 fault states under mixed working conditions by manually extracting 19 features. In reference [26], the author utilized eight wavelet packet energy with multifractal features (8WPE-MF) to train SVMs and to realize 10 fault states diagnosed under mixed working conditions.…”

“…As a robust classification methodology, support vector machine (SVM) [2] has been successfully used in the applications of bearing fault diagnosis over recent years [3][4][5][6]. Given two sample sets, the classical SVM is aimed at constructing an optimal separating hyper-plane that maximizes the geometric margin between the hyper-plane and its closest samples from the two sample sets [2].…”

“…Fractal features have been widely used in texture analysis, signal analysis, object modeling and image classification, etc. [2][3][4][5]. The multifractal spectrum reveals deep structure features of images and improves the performance of traditional image processing methods.…”
