On Tikhonov Regularization, Bias and Variance in Nonlinear System Identification
, 1997 this paper we study Tikhonov regularization (Tikhonov and Arsenin 1977). While Tikhonov regularization has had significant impact on several branches of science and engineering dealing with ill-posed and inverse problems, in particular modeling and ...

Approximate controllability of a semilinear delayed heat equation Tikhonov regularization
Современная математика: Фундаментальные направленияIn this work, we study approximate controllability of a semilinear heat equation with delay using the Tikhonov regularization. The considered problem for partial differential equation is transformed into an equivalent operator equation.

Adaptive Arnoldi-Tikhonov regularization for image restoration
, 2014 In the framework of the numerical solution of linear systems arising from image restoration, in this paper we present an adaptive approach based on the reordering of the image approximations obtained with the Arnoldi-Tikhonov method.

The Application of Piecewise Regularization Reconstruction to the Calibration of Strain Beams
SensorsStandard beams are mainly used for the calibration of strain sensors using their load reconstruction models. However, as an ill-posed inverse problem, the solution to these models often fails to converge, especially when dealing with dynamic loads of ...

Regularización de Tikhonov para estimar los parámetros de un modelo de un horno de arco
Tecnura, 2013 In this paper, we present a methodology for estimating the parameters of a model for an electrical arc furnace by using Tikhonov regularization. Tikhonov regularization is one of the most widely employed methods for regularization. The model proposed for

, 2017 We study Tikhonov regularization for ill-posed non-linear operator equations in Hilbert scales. Our focus is on the interplay between the smoothness-promoting properties of the penalty and the smoothness inherent in the solution.

Tikhonov regularization with nonnegativity constraint
, 2008 . Many numerical methods for the solution of ill-posed problems are based on Tikhonov regularization. Recently, Rojas and Steihaug [15] described a barrier method for computing nonnegative Tikhonov-regularized approximate solutions of linear discrete ill-
