Shortfall-Based Wasserstein Distributionally Robust Optimization

open access: yesMathematics, 2023
In this paper, we study a distributionally robust optimization (DRO) problem with affine decision rules. In particular, we construct an ambiguity set based on a new family of Wasserstein metrics, shortfall–Wasserstein metrics, which apply normalized ...

The Distributionally Robust Optimization Reformulation for Stochastic Complementarity Problems

open access: yesAbstract and Applied Analysis, 2014
We investigate the stochastic linear complementarity problem affinely affected by the uncertain parameters. Assuming that we have only limited information about the uncertain parameters, such as the first two moments or the first two moments as well as ...

Distributionally robust learning-to-rank under the Wasserstein metric

open access: yesPLoS ONE, 2023
Despite their satisfactory performance, most existing listwise Learning-To-Rank (LTR) models do not consider the crucial issue of robustness. A data set can be contaminated in various ways, including human error in labeling or annotation, distributional ...
