4 Singular Value Decomposition (SVD) - Princeton University

www.cs.princeton.edu

4 Singular Value Decomposition (SVD) The singular value decomposition of a matrix A is the factorization of A into the product of three matrices A = UDVT where the columns of U and V are orthonormal and the matrix D is diagonal with positive real entries. The SVD is useful in many tasks. Here we mention two examples.

Singular Value Decomposition • Total least squares • Practical notes . Review: Condition Number • Cond(A) is function of A • Cond(A) >= 1, bigger is bad • Measures how change in input is propogated to change in output • E.g., if cond(A) = 451 then can lose log(451)= 2.65 digits of accuracy in x, compared to ...

solve it using Singular Value Decomposition (SVD). Starting with equation 13 from the previous section, we rst compute the SVD of A: A = U V> = X9 i=1 ˙iu iv > (17) When performed in Matlab, the singular values ˙i will be sorted in descending order, so ˙9 will be the smallest. There are three cases for the value of ˙9:

matrix is to utilize the singular value decomposition of S = A0A where A is a matrix consisting of the eigenvectors of S and is a diagonal matrix whose diagonal elements are the eigenvalues corresponding to each eigenvector. Creating a reduced dimensionality projection of X is accomplished by selecting the q largest eigenvalues in and retaining ...

We cover singular-value decomposition, a more powerful version of UV-decomposition. Finally, because we are always interested in the largest data sizes we can handle, we look at another form of decomposition, called CUR-decomposition, which is a variant of singular-value decomposition that keeps the matrices of the decomposition sparse if the

continuous. Moreover, the above decomposition is unique. Let λ denote the Lebesgue measure on B, the σ-field of Borel sets in R. It follows from the Lebesgue decomposition theorem that we can write F c(x) = βF s(x)+(1−β)F ac(x) where 0 ≤ β ≤ 1, F s is singular with respect to λ, and F ac is absolutely continuous with respect to λ.
