Divide-and-Conquer Matrix Factorization
Divide-and-Conquer Matrix Factorization Numerical Analysis
2011/9/29
Abstract: This work introduces SubMF, a parallel divide-and-conquer framework for noisy matrix factorization. SubMF divides a large-scale matrix factorization task into smaller subproblems, solves eac...
Improvements on Cantor-Zassenhaus Factorization Algorithm
Polynomial factorization Cantor-Zassenhaus
2011/2/25
After revisiting Cantor-Zassenhaus polynomial factorization algorithm, we describe a new
simplified version of it, which requires less computational cost.
Let X V be a closed embedding, with V r X nonsingular. We de ne a constructible function X;V on X, agreeing with Verdier's specialization of the constant function 11V when X is the zero-locus of a ...
