Keywords: | Discrepancy principle; General-form Tikhonov regularization; Ill-posedness; Least squares | Issue Date: | 23-Sep-2011 | Publisher: | American Elsevier Publ. | Source: | Linear Algebra and Its Applications 8 (436): 2845-2865 (2012) | Abstract (english): | This paper presents a new approach to computing an approximate solution of Tikhonov-regularized large-scale ill-posed least-squares problems with a general regularization matrix. The iterative method applies a sequence of projections onto generalized Krylov subspaces. A suitable value of the regularization parameter is determined by the discrepancy principle. |
