A Convex Constraint Variational Method for Restoring Blurred Images in the Presence of Alpha-Stable Noises [PDF]
Sensors, 2018 Blurred image restoration poses a great challenge under the non-Gaussian noise environments in various communication systems. In order to restore images from blur and alpha-stable noise while also preserving their edges, this paper proposes a variational

The variational method of moments
Journal of the Royal Statistical Society Series B: Statistical Methodology, 2023 Abstract The conditional moment problem is a powerful formulation for describing structural causal parameters in terms of observables, a prominent example being instrumental variable regression. We introduce a very general class of estimators called the variational method of moments (VMM), motivated by a variational minimax reformulation

Exponential type duality for η-approximated variational problems [PDF]
Yugoslav Journal of Operations Research, 2020 In this article, we use the so-called η-approximation method for solving a new class of nonconvex variational problems with exponential (p, r)-invex functionals.
