A Regularization Parameter in Discrete Ill-Posed Problems

SIAM Journal of Scientific Computing, 1996
The author considers the Tikhonov regularization method for the discrete ill-posed problem of minimizing \[ J_\alpha(u)=|Ku-f|^2+\alpha|u|^2, \] where \(K\) is an \(m\times n\) matrix with a large condition number, \(m\geq n\), and \(\alpha>0\). The Euclidean norm is used.

On the discrete linear ill‐posed problems

open access: yesMathematical Modelling and Analysis, 1999
An inverse problem of photo‐acoustic spectroscopy of semiconductors is investigated. The main problem is formulated as the integral equation of the first kind.

Ill-posed inverse problems in economics [PDF]

open access: yesAnnual Review of Economics, 2013
A parameter of an econometric model is identified if there is a one-to-one or many-to-one mapping from the population distribution of the available data to the parameter.

Noise Models for Ill-Posed Problems

open access: yes, 2014
The standard view of noise in ill-posed problems is that it is either deterministic and small (strongly bounded noise) or random and large (not necessarily small).

Economic Cycles of Carnot Type

open access: yesEntropy, 2021
Originally, the Carnot cycle was a theoretical thermodynamic cycle that provided an upper limit on the efficiency that any classical thermodynamic engine can achieve during the conversion of heat into work, or conversely, the efficiency of a ...

Convergence of the grid method for the Fredholm equation of the first kind with Tikhonov regularization

open access: yesDiscrete and Continuous Models and Applied Computational Science, 2023
The paper describes a grid method for solving an ill-posed problem for the Fredholm equation of the first kind using the A. N. Tikhonov regularizer. The convergence theorem for this method was formulated and proved.
