Parameter Choice Strategies for Multipenalty Regularization
The widespread applicability of the multi-penalty regularization is limited by the fact that theoretically optimal rate of reconstruction for a given problem can be realized by a oneparameter counterpart, provided that relevant information on the problem is available and taken into account in the regularization. In this paper, we explore the situation, where no such information is given, but st...
متن کاملA Parameter Choice Method for Tikhonov Regularization
Abstract. A new parameter choice method for Tikhonov regularization of discrete ill-posed problems is presented. Some of the regularized solutions of a discrete ill-posed problem are less sensitive than others to the perturbations in the right-hand side vector. This method chooses one of the insensitive regularized solutions using a certain criterion. Numerical experiments show that the new met...
متن کاملComparing parameter choice methods for regularization of ill-posed problems
In the literature on regularization, many different parameter choice methods have been proposed in both deterministic and stochastic settings. However, based on the available information, it is not always easy to know how well a particular method will perform in a given situation and how it compares to other methods. This paper reviews most of the existing parameter choice methods, and evaluate...
متن کاملA Regularization Parameter for Nonsmooth Tikhonov Regularization
In this paper we develop a novel criterion for choosing regularization parameters for nonsmooth Tikhonov functionals. The proposed criterion is solely based on the value function, and thus applicable to a broad range of functionals. It is analytically compared with the local minimum criterion, and a posteriori error estimates are derived. An efficient numerical algorithm for computing the minim...
متن کاملΧ Tests for the Choice of the Regularization Parameter in Nonlinear Inverse Problems∗
We address discrete nonlinear inverse problems with weighted least squares and Tikhonov regularization. Regularization is a way to add more information to the problem when it is ill-posed or ill-conditioned. However, it is still an open question as to how to weight this information. The discrepancy principle considers the residual norm to determine the regularization weight or parameter, while ...
