Morozov's Discrepancy Principle for Tikhonov Regularization of Severely Ill-posed Problems in Nite-dimensional Subspaces
نویسندگان
چکیده
In this paper severely ill-posed problems are studied which are represented in the form of linear operator equations with innnitely smoothing operators but with solutions having only a nite smoothness. It is well known, that the combination of Morozov's discrepancy principle and a nite dimensional version of the ordinary Tikhonov regularization is not always optimal because of its saturation property. Here it is shown, that this combination is always order-optimal in the case of severely ill-posed problems.

Applications of the Modified Discrepancy Principle to Tikhonov Regularization of Nonlinear Ill-posed Problems∗
In this paper, we consider the finite-dimensional approximations of Tikhonov regularization for nonlinear ill-posed problems with approximately given right-hand sides. We propose an a posteriori parameter choice strategy, which is a modified form of Morozov’s discrepancy principle, to choose the regularization parameter. Under certain assumptions on the nonlinear operator, we obtain the converg...
متن کاملUsing the L{curve for Determining Optimal Regularization Parameters
The \L{curve" is a plot (in ordinary or doubly{logarithmic scale) of the norm of (Tikhonov{) regularized solutions of an ill{posed problem versus the norm of the residuals. We show that the popular criterion of choosing the parameter corresponding to the point with maximal curvature of the L{curve does not yield a convergent regularization strategy to solve the ill{posed problem. Nevertheless, ...

The methods applied to regularization of the ill-posed problems can be classified under “direct” and “indirect” methods. Practice has shown that the effects of different regularization techniques on an ill-posed problem are not the same, and as such each ill-posed problem requires its own investigation in order to identify its most suitable regularization method. In the geoid computations witho...
متن کاملA new framework for multi-parameter regularization
This paper proposes a new approach for choosing the regularization parameters in multiparameter regularization methods when applied to approximate the solution of linear discrete ill-posed problems. We consider both direct methods, such as Tikhonov regularization with two or more regularization terms, and iterative methods based on the projection of a Tikhonov-regularized problem onto Krylov su...
متن کاملIll-Posed and Linear Inverse Problems
In this paper ill-posed linear inverse problems that arises in many applications is considered. The instability of special kind of these problems and it's relation to the kernel, is described. For finding a stable solution to these problems we need some kind of regularization that is presented. The results have been applied for a singular equation.
