A discrepancy principle for Poisson data
Inverse Problems, 2010In applications of imaging science, such as emission tomography, fluorescence microscopy and optical/infrared astronomy, image intensity is measured via the counting of incident particles (photons, γ-rays, etc). Fluctuations in the emission-counting process can be described by modeling the data as realizations of Poisson random variables (Poisson data).

A generalized discrepancy principle for solving incompatible equations
USSR Computational Mathematics and Mathematical Physics, 1984Let \(Z\) be a reflexive Banach space with the property \(H\), \(D\) be a closed convex subset of \(Z\), \(0\in D\). Consider an incompatible equation \(Az=u\) in \(D\) (i.e. \(\mu =\inf \{\| Az-u\|: z\in D\}\ge 0)\) where \(A\) is a bounded linear operator from \(Z\) into a normed linear space \(U\), \(u\in U\), and suppose there is a normal ...

On convergence rates for asymptotic discrepancy principle
Journal of Inverse and Ill-posed Problems, 2016Abstract A series of recent numerical experiments for parameter estimation inverse problems in epidemiology [7, 6] have indicated that applicability of the discrepancy principle (DP) does not depend on the structure of a particular regularizing operator.

Principles of orthognathic management of dentofacial discrepancies
Dental Update, 2018Abstract: Individuals with severe dentofacial discrepancies that are beyond the scope of conventional orthodontic treatment will often require a joint orthodontic-surgical approach to manage their malocclusion. This treatment approach involving orthodontics in combination with orthognathic surgery is used to manage severe underlying skeletal ...

Comments on Morozov’s Discrepancy Principle
1983The choice of regularization parameter by Morozov’s principle is characterized in a new way and is related to another parameter choice strategy. An asymptotic order of accuracy is derived which is essentially best possible and a discrepancy principle is developed in a finite element context.

Heuristic discrepancy principle for variational regularization of inverse problems
Inverse Problems, 2020Abstract We consider the variational regularization for inverse problems in a general form. Based on the discrepancy principle, we propose a heuristic parameter choice rule for choosing the regularization parameter which does not require the information on the noise level and is therefore purely data driven.
