    en.wikipedia.org/wiki/Higher-order_singular...

    In multilinear algebra, the higher-order singular value decomposition (HOSVD) of a tensor is a specific orthogonal Tucker decomposition. It may be regarded as one type of generalization of the matrix singular value decomposition. It has applications in computer vision, computer graphics, machine learning, scientific computing, and signal ...

  4. Singular value - Wikipedia

    en.wikipedia.org/wiki/Singular_value

    The singular values are non-negative real numbers, usually listed in decreasing order (σ 1 (T), σ 2 (T), …). The largest singular value σ 1 (T) is equal to the operator norm of T (see Min-max theorem). Visualization of a singular value decomposition (SVD) of a 2-dimensional, real shearing matrix M.

    In linear algebra, two-dimensional singular-value decomposition (2DSVD) computes the low-rank approximation of a set of matrices such as 2D images or weather maps in a manner almost identical to SVD (singular-value decomposition) which computes the low-rank approximation of a single matrix (or a set of 1D vectors).

    An alternative decomposition of X is the singular value decomposition (SVD) [1] X = U Σ V T {\displaystyle X=U\Sigma V^{\rm {T}}\ } , where U is m by m orthogonal matrix, V is n by n orthogonal matrix and Σ {\displaystyle \Sigma } is an m by n matrix with all its elements outside of the main diagonal equal to 0 .

  9. Generalized singular value decomposition - Wikipedia

    en.wikipedia.org/wiki/Generalized_singular_value...

    In linear algebra, the generalized singular value decomposition (GSVD) is the name of two different techniques based on the singular value decomposition (SVD).The two versions differ because one version decomposes two matrices (somewhat like the higher-order or tensor SVD) and the other version uses a set of constraints imposed on the left and right singular vectors of a single-matrix SVD.
