Problem-driven scenario clustering in stochastic optimization

J Keutchayan, J Ortmann, W Rei - Computational Management Science, 2023 - Springer
In stochastic optimisation, the large number of scenarios required to faithfully represent the
underlying uncertainty is often a barrier to finding efficient numerical solutions. This …

Low budget active learning via wasserstein distance: An integer programming approach

R Mahmood, S Fidler, MT Law - arxiv preprint arxiv:2106.02968, 2021 - arxiv.org
Active learning is the process of training a model with limited labeled data by selecting a
core subset of an unlabeled data pool to label. The large scale of data sets used in deep …

Optimizing the inventory and fulfillment of an omnichannel retailer: a stochastic approach with scenario clustering

A Abouelrous, AF Gabor, Y Zhang - Computers & Industrial Engineering, 2022 - Elsevier
We study an inventory optimization problem for a retailer that faces stochastic online and in-
store demand in a selling season of fixed length. The retailer has to decide the initial …

Optimal scenario reduction for one-and two-stage robust optimization with discrete uncertainty in the objective

M Goerigk, M Khosravi - European Journal of Operational Research, 2023 - Elsevier
Robust optimization typically follows a worst-case perspective, where a single scenario may
determine the objective value of a given solution. Accordingly, it is a challenging task to …

Semi-discrete optimal transport: Hardness, regularization and numerical solution
