Webbbe greater than the product of the spectral norms of these two tensors. In Section 4, we give a counterexample to illustrate this. Then, as a substitute, in that section, we show that the spectral norm of the tensor product of two tensors is not greater than the product of the spectral norm of one tensor, and the nuclear norm of another tensor. WebbWe obtain the optimized small-scale spectral tensor by the minimization of original and reconstructed three-dimension spectral tensor in self-learning CNNs. Then, the NTD is applied to the optimized three-dimension spectral tensor in the DCT domain to obtain the high compression performance.
