# Modified Gauss-Newton method in low-rank signal estimation

@article{Zvonarev2018ModifiedGM, title={Modified Gauss-Newton method in low-rank signal estimation}, author={N. Zvonarev and N. Golyandina}, journal={arXiv: Numerical Analysis}, year={2018} }

The paper is devoted to the solution of a weighted non-linear least-squares problem for low-rank signal estimation, which is related Hankel structured low-rank approximation problems. The solution is constructed by a modified weighted Gauss-Newton method. The advantage of the suggested method is the possibility of its stable and fast implementation. The method is compared with a known method, which uses the variable-projection approach, by stability, accuracy and computational cost. For the… Expand
