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.

A new interpretation of (Tikhonov) regularization [PDF]

open access: yesInverse Problems, 2021
Abstract Tikhonov regularization with square-norm penalty for linear forward operators has been studied extensively in the literature. However, the results on convergence theory are based on technical proofs and sometimes difficult to interpret.

Fractional Regularized Distorted Born Iterative Method for Permittivity Reconstruction [PDF]

open access: yesRadioengineering, 2022
In this paper, we propose a fractional regularized distorted Born iterative method (DBIM) to solve non-linear ill-posed problems of microwave imaging.

DIAS: A Data-Informed Active Subspace Regularization Framework for Inverse Problems

open access: yesComputation, 2022
This paper presents a regularization framework that aims to improve the fidelity of Tikhonov inverse solutions. At the heart of the framework is the data-informed regularization idea that only data-uninformed parameters need to be regularized, while the ...

Multi-parameter Tikhonov regularization [PDF]

open access: yesMethods and Applications of Analysis, 2011
We study multi-parameter Tikhonov regularization, i.e., with multiple penalties. Such models are useful when the sought-for solution exhibits several distinct features simultaneously. Two choice rules, i.e., discrepancy principle and balancing principle, are studied for choosing an appropriate (vector-valued) regularization parameter, and some ...

On the convergence of algorithms with Tikhonov regularization terms [PDF]

open access: yesOptimization Letters, 2020
We consider the strongly convergent modified versions of the Krasnosel'ski\uı-Mann, the forward-backward and the Douglas-Rachford algorithms with Tikhonov regularization terms, introduced by Radu Boţ, Ernö Csetnek and Dennis Meier. We obtain quantitative information for these modified iterations, namely rates of asymptotic regularity and metastability.

Intelligent Particle Swarm Optimization Method for Parameter Selecting in Regularization Method for Integral Equation [PDF]

open access: yesBIO Web of Conferences
We use the Tikhonov method as a regularization technique for solving the integral equation of the first kind with noisy and noise-free data. Following that, we go over how to choose the Tikhonov regularization parameter by implementing the Intelligent ...

An Adaptive Image Denoising Model Based on Tikhonov and TV Regularizations

open access: yesAdvances in Multimedia, 2014
To avoid the staircase artifacts, an adaptive image denoising model is proposed by the weighted combination of Tikhonov regularization and total variation regularization.

Tikhonov Regularization and Total Least Squares [PDF]

open access: yesSIAM Journal on Matrix Analysis and Applications, 1999
The regularized total least squares (TLS) method of the TLS problem is introduced and its regularizing properties are studied. It is also proved that, in certain cases, the new method is superior to standard regularization methods.

Bayesian regularization: From Tikhonov to horseshoe [PDF]

open access: yesWIREs Computational Statistics, 2019
Bayesian regularization is a central tool in modern‐day statistical and machine learning methods. Many applications involve high‐dimensional sparse signal recovery problems. The goal of our paper is to provide a review of the literature on penalty‐based regularization approaches, from Tikhonov (Ridge, Lasso) to horseshoe regularization.This article is ...
