(mathematics) A process by which a rectangular table of numbers or abstract quantities that can be added and multiplied is broken down into simpler numerical 

Suppose that the given data are arranged as the columns of a large matrix X = [x 1; ;x n] 2Rd n. A general assumption is that there is a low-dimensional subspace, or a union of multiple subspaces hidden in X. That is, there exists a dictionary matrix D = [d 1; ;d r] 2Rd rand corresponding codes C = [c 1; ;c n] 2Rr nthat X can be … SVD summary: •The SVD is a factorization of a (×*matrix into !=,-.#where,is a (×( orthogonal matrix,.#is a *×*orthogonal matrix and -is a (×*diagonal matrix. •In reduced form:!=, $ #, where , is a (×/matrix, -. is a /×/matrix, and . is a *×/matrix, and /=min((,*). and D is the diagonal matrix with diagonal entries λ 1,···,λ n.TheequationA = PDPT can be rewritten as: A = [u 1 ··· u n]! λ 1 λ n " ⎡ ⎣ uT..1.

Of course the truncated SVD is no longer an exact decomposition of the original matrix M, but as discussed above, the approximate matrix ~ is in a very useful sense the closest approximation to M that can be achieved by a matrix of rank t. “Matrix decomposition refers to the transformation of a given matrix into a given canonical form.” [1], when the given matrix is transformed to a right-hand-side product of canonical matrices the process of producing this decomposition is also called “matrix factorization”. Matrix decomposition is a fundamen- Singular Value Decomposition The SVD is a factorization of a !×#matrix into $=&’(! where&is a !×!orthogonal matrix,(!is a #×#orthogonal matrix and ’is a !×#diagonal matrix. The first of these, Theorem 18.1.1, gives the basic factorization of a square real-valued matrix into three factors. The second, Theorem 18.1.1 , applies to square symmetric matrices and is the basis of the singular value decomposition described in Theorem 18.2 . SVD is the most versatile decomposition of a general matrix.

by Marco Taboga, PhD. The QR decomposition (or QR factorization) allows to express a matrix having linearly independent columns as the product of 1) a matrix Q having orthonormal columns and 2) an upper triangular matrix R. In order to fully understand how the QR decomposition is obtained, we should be familiar with the Gram-Schmidt process. Let's denote these square block of matrix U_1 by E and this square block of D by F and let's provide a different decomposition for this matrix, a decomposition of this sort.

A penalized matrix decomposition 517 where M(r) is the set of rank-rn× p matrices and · 2 F indicates the squared Frobenius norm (the sum of squared elements of the matrix). In other words, the first r components of the SVD give the best rank-r approximation to a matrix, in the sense of the Frobenius norm.
