Extension of Tikhonov regularization method using linear fractional programming

Journal of Computational and Applied Mathematics, 2020
Given a real $m\times n$ matrix $A$ with $m\geq n$ and a noisy vector $b$, this paper focuses on the following least-squares problem: $\min_{x\in \mathbb{R}^n}\|Ax-b\|^2$. Here $\|\cdot\|$ is the Euclidean norm. This problem is commonly studied in the framework of the Tikhonov regularization which consists of solving the regularized least-squares ...

Convergence Rates of the Hilbert Uniqueness Method via Tikhonov Regularization

Journal of Optimization Theory and Applications, 1999
A parabolic differential equation on \([0,1]\times [0,T]\) with Dirichlet data and homogeneous initial data of the following form is considered \[ {\partial y\over\partial t}-{\partial\over\partial x} \Biggl(a(x){\partial y\over\partial x}\Biggr)= 0, \] \[ y(0,x)= 0,\quad y(t,0)= \nu_0(t),\quad y(t,1)= \nu_1(t), \] with diffusion coefficient \(a(x)\in ...

An Improved Tikhonov Regularization Method for Conductivity Tomography Imaging

2008 International Symposium on Computer Science and Computational Technology, 2008
Discretizations of inverse problem lead to systems of linear equations with a highly ill-conditioned coefficient matrix, and in order to compute stable solutions to these systems it is necessary to apply regularization methods. This paper compares our improved Tikhonov regularization algorithm to several existing regularization methods, which are ...

New intermediate view synthesis method based on Tikhonov regularization

IEEE 10th INTERNATIONAL CONFERENCE ON SIGNAL PROCESSING PROCEEDINGS, 2010
The intermediate view synthesis from arbitrary view is a challenging topic in multi-view areas, many image-based rendering methods have been proposed to solve this problem. A new multi-view intermediate view synthesis method based on Tikhonov regularization function is proposed to synthesis view from limited number of source views. The experiments show

Genetic Algorithm Based Tikhonov Regularization Method for Displacement Reconstruction

Journal of Shanghai Jiaotong University (Science), 2019
In this paper, a genetic algorithm based Tikhonov regularization method is proposed for determination of globally optimal regularization factor in displacement reconstruction. Optimization mathematic models are built by using the generalized cross-validation (GCV) criterion, L-curve criterion and Engl’s error minimization (EEM) criterion as the ...

Tikhonov-regularized bispectral variational method for optical signal reconstruction

Computational Mathematics and Modeling, 2013
A Tikhonov-regularized bispectral variational method is proposed for image restoration in the presence of strong phase distortions. This method combines a number of advantages of the bispectral approach, such as preservation and restoration of phase information, invariance to random shifts of the original signal, and no requirement of high-accuracy ...
