Web2.1. High Order SVD In SVD, a matrix or order-2 tensor A can be decomposed as matrix product: A = U 1 U T 2. This matrix product can be rewritten as[4] A = × 1 U 1 × 2 U 2. (2) By extension, a tensor A of order N > 2 is an N-dimensional matrixcomprisingNspaces. HighOrderSVD(HOSVD) is an extension of SVD that orthogonalizes these N spaces and WebThe tensor tubal rank, defined based on the tensor singular value decomposition (t-SVD), has obtained promising results in hyperspectral image (HSI) denoising. ...
