- W1432955279 abstract "We propose new techniques and algorithms that advance the known methods for a number of fundamental problems of matrix computations. These problems includes approximation of leading and trailing singular spaces of a matrix with extensions to derandomized approximation by low-rank matrices and by structured matrices, support for numerically safe Gaussian elimination with no pivoting, and devising effective preconditioners that cover the general class of matrices having a small numerical nullity or a small numerical rank. Our technical novelties include randomized additive preconditioning and augmentation for general and structured matrices, derandomization, and dual extension of the Sherman–Morrison–Woodbury formula. Our extensive tests demonstrate effectiveness of the proposed algorithms." @default.
