Linear maximum margin tensor classification based on flexible convex hulls for fault diagnosis of rolling bearings

作者:

Highlights:

• A new tensor classifier called MMTC-FCH is proposed and applied to the fault diagnosis of rolling bearings.

• CP decomposition has been applied to the calculation process of tensor inner product.

• The reduction factor is used to improve the robustness of MMTC-FCH.

• Wavelet time–frequency grayscale images are used as second-order feature tensors.

• Experimental results show that MMTC-FCH is superior to the classifiers of the vector space.
