    The Application of Orthogonal Wavelet Transformation: Support Vector Data Description in Evaluating the Performance and Health of Bearings by Weipeng Li, Yan Cao, Lijuan Li, Siyu Hou

    Published 2022-01-01
    “…In this paper, an orthogonal wavelet transformation-support vector data description (OWTSVDD) is proposed to evaluate the performance of bearings, where the peak-to-peak value of detail signal is extracted through orthogonal wavelet transformation as the set of test samples, thus solving the distance Rz from the set of test samples to the center of the sphere. Based on HI=Rz2−R2, its distance to the hypersphere is calculated to judge whether it belongs to the normal state training samples. …”
