Journal ArticleDOI
Algorithm for model validation: Theory and applications
TL;DR: This work proposes to formulate the validation of a given model as an iterative construction process that mimics the often implicit process occurring in the minds of scientists, and offers a formal representation of the progressive build-up of trust in the model.
Journal ArticleDOI
Graduated adaptive image denoising: local compromise between total variation and isotropic diffusion
TL;DR: Variations of the variational image denoising method proposed by Blomgren et al are introduced and existence and (where appropriate) uniqueness of minimizers are proved.
A Gradient Descent Solution to the Monge-Kantorovich Problem
TL;DR: In this article, the authors present an algorithm for computing the optimal mapping for the monge-kantorovich problem with quadratic cost, based on a reformulation of the dual problem into an unconstrained minimization of a convex, continuous functional, for which the derivative can be explicitly found.
Journal ArticleDOI
From classical to modern opinion dynamics
TL;DR: In this age of Facebook, Instagram, and Twitter, there is rapidly growing interest in understanding network-enabled opinion dynamics in large groups of autonomous agents as discussed by the authors, and the phenomena of opinion p...

TL;DR: In this paper, the accuracy of density measurements and position resolution in flash (40 ns) radiography of thick objects with 24 Gev/c protons was investigated and a global model fit to step wedge data was shown to give a good description spanning the periodic table.
