T-svd based tensor nuclear norm

WebAbstract. A flexible transform-based tensor product named ★ QT-product for Lth-order (L ≥ 3) quaternion tensors is proposed. Based on the ★ QT-product, we define the corresponding singular value decomposition named TQt-SVD and the rank named TQt-rank of the Lth-order (L ≥ 3) quaternion tensor. WebDespite the promising preliminary results, tensor-singular value decomposition (t-SVD)-based multiview subspace is incapable of dealing with real problems, such as noise and …
