Variational regularization for systems of inverse problems: Tikhonov regularization with multiple forward operators

, 2019
Tikhonov regularization is a cornerstone technique in solving inverse problems with applications in countless scientific fields. Richard Huber discusses a multi-parameter Tikhonov approach for systems of inverse problems in order to take advantage of their

Improved Tikhonov regularization method for load identification and structural response reconstruction

Jixie qiangdu
To improve the accuracy and efficiency of load identification and structural response reconstruction, an improved Tikhonov regularization method that simultaneously considers transfer matrix error and measurement error was proposed.

Source Conditions for Non-Quadratic Tikhonov Regularization

, 2020
In this paper, we consider convex Tikhonov regularization for the solution of linear operator equations on Hilbert spaces. We show that standard fractional source conditions can be employed in order to derive convergence rates in terms of the Bregman ...

Infinite-σ Limits For Tikhonov Regularization

, 2008
We consider the problem of Tikhonov regularization with a general convex loss function: this formalism includes support vector machines and regularized least squares.

Inexact searches on the L-curve

Publicaciones en Ciencias y Tecnología, 2009
In a Tikhonov regularization scheme to solve discrete linear ill-posed problems, selecting the parameter value is a key task. We use Wolfe inexact search on the L-curve to choose a λ regularization parameter value far from critical areas of the L-curve ...
