A GCV based Arnoldi-Tikhonov regularization method [PDF]

open access: yesBIT Numerical Mathematics, 2013
For the solution of linear discrete ill-posed problems, in this paper we consider the Arnoldi-Tikhonov method coupled with the Generalized Cross Validation for the computation of the regularization parameter at each iteration. We study the convergence behavior of the Arnoldi method and its properties for the approximation of the (generalized) singular ...

Arnoldi–Tikhonov regularization methods [PDF]

open access: yesJournal of Computational and Applied Mathematics, 2009
The problem is to solve a large, ill-conditioned linear system \(Ax=b\) of size \(n\), where \(b=\hat{b}+e\) with \(\hat{b}\) the ``true'' vector and \(e\) some error. Tikhonov regularization minimizes \(\|Ax-b\|^2+\mu^{-1}\|x\|\) with \(\mu\) a regularization parameter.

An Improved Tikhonov-Regularized Variable Projection Algorithm for Separable Nonlinear Least Squares

open access: yesAxioms, 2021
In this work, we investigate the ill-conditioned problem of a separable, nonlinear least squares model by using the variable projection method. Based on the truncated singular value decomposition method and the Tikhonov regularization method, we propose ...

Tikhonov regularized iterative methods for nonlinear problems

open access: yesOptimization, 2023
We consider the monotone inclusion problems in real Hilbert spaces. Proximal splitting algorithms are very popular technique to solve it and generally achieve weak convergence under mild assumptions. Researchers assume the strong conditions like strong convexity or strong monotonicity on the considered operators to prove strong convergence of the ...

A Combined Use of TSVD and Tikhonov Regularization for Mass Flux Solution in Tibetan Plateau

open access: yesRemote Sensing, 2020
Limited by the Gravity Recovery and Climate Experiment (GRACE) and GRACE Follow-On (GRACE-FO) measurement principle and sensors, the spatial resolution of mass flux solutions is about 2–3° in mid-latitudes at monthly intervals.

The Tikhonov regularization method in elastoplasticity

open access: yesApplied Mathematical Modelling, 2012
The numeric simulation of the mechanical behaviour of industrial materials is widely used in the companies for viability verification, improvement and optimization of designs. The eslastoplastic models have been used for forecast of the mechanical behaviour of materials of the most several natures (see [1]).
