It encounters the challenge raised by the rapid development of Internet and information technology, which is difficult to train the classifier because of the limit sample compared to huge unknown data, and to simulate the space distribution of samples. This may raise the problems of over fitting and unbalanced data. Tensor representation is helpful to
