Rolling bearing vibration data and their labels are difficult or impossible to obtain under varying working conditions. Thus, multistats identification of different fault positions and degradation degrees has relatively low accuracy. This paper propo

There are several issues with existing chaotic encryption schemes for images. These include singularity, unidirectionality, and the complexity of the algorithm. The result is that the encrypted image has low security and acquiring discrete chaotic se

In practical applications, it is difficult to obtain enough fault samples to train a fault classification model for rolling bearings, and the specifications of bearings used in different mechanical equipment may be different. The diagnosis model trai

Sphere structured support vector machine is a multi-classification algorithm. The algorithm separately constructs sphere for each class sample data, so the complex degree of the quadratic programming is reduced and it is easier to extend new samples.
