1. Gauss-Newton method replaces nonlinear least squares problem by sequence of linear least squares problems whose solutions converge to solution of original nonlinear problem. 2. If residual at solution is large, then second-order term omitted from hessian is not negligible, and Gauss-Newton metho...
内容提示: A Randomised Subspace Gauss-Newton Method for Nonlinear Least-SquaresCoralia Cartis 1 2 * Jaroslav Fowkes 1 * Zhen Shao 1 *AbstractWe propose a Randomised Subspace Gauss-Newton (R-SGN) algorithm for solving nonlin-ear least-squares optimization problems, that usesa sketched Jacobian of...
This work proposes a structured diagonal Gauss–Newton algorithm for solving zero residue nonlinear least-squares problems. The matrix corresponding to the Gauss–Newton direction is approximated with a diagonal matrix that satisfies the structured secant condition. Using a derivative-free Armijo-type ...
