Truncated svd for faster detection
http://proceedings.mlr.press/v95/feng18a/feng18a.pdf WebSep 15, 2024 · The SVD of a matrix A is a factorization of A into three new matrices U, D , and V, such that, where matrices U and V have orthonormal columns, and D is a diagonal matrix of singular values. SVD calculates only the first k columns of these matrices ( U, D , and V ). This is called the truncated decomposition of the original matrix.
