Block SOR methods for rank-de cient least-squares problems
Many papers have discussed preconditioned block iterative methods for solving full rank least-squares problems. However very few papers studied iterative methods for solving rank-de cient least-squares problems. Miller and Neumann (1987) proposed the 4-block SOR method for solving the rank-de cient problem. Here a 2-block SOR method and a 3-block SOR method are proposed to solve such problem. T...
متن کاملA note on sparse least-squares regression
We compute a sparse solution to the classical least-squares problem minx ‖Ax−b‖2, where A is an arbitrary matrix. We describe a novel algorithm for this sparse least-squares problem. The algorithm operates as follows: first, it selects columns from A, and then solves a least-squares problem only with the selected columns. The column selection algorithm that we use is known to perform well for t...
متن کاملTensor Methods for Large, Sparse Nonlinear Least Squares Problems
This paper introduces tensor methods for solving large, sparse nonlinear least squares problems where the Jacobian either is analytically available or is computed by nite diier-ence approximations. Tensor methods have been shown to have very good computational performance for small to medium-sized, dense nonlinear least squares problems. In this paper we consider the application of tensor metho...
متن کاملA Multilevel Block Incomplete Cholesky Preconditioner for Solving Rectangular Sparse Matrices from Linear Least Squares Problems
An incomplete factorization method for preconditioning symmetric positive definite matrices is introduced to solve normal equations. The normal equations are formed as a means to solve rectangular matrices from linear least squares problems. The procedure is based on a block incomplete Cholesky factorization and a multilevel recursive strategy with an approximate Schur complement matrix formed ...
متن کاملGMRES Methods for Least Squares Problems
The standard iterative method for solving large sparse least squares problems min ∈Rn ‖ −A ‖2, A ∈ Rm×n is the CGLS method, or its stabilized version LSQR, which applies the (preconditioned) conjugate gradient method to the normal equation ATA = AT . In this paper, we will consider alternative methods using a matrix B ∈ Rn×m and applying the Generalized Minimal Residual (GMRES) method to min ∈R...
