Designing Ambiguity Sets for Distributionally Robust Optimization Using Structural Causal Optimal Transport

AAAI 2025technical

Distributionally robust optimization tackles out-of-sample issues like overfitting and distribution shifts by adopting an adversarial approach over a range of possible data distributions, known as the ambiguity set. To balance conservatism and accuracy, these sets must include realistic probability…

Wasserstein Distributionally Robust Optimization through the Lens of Structural Causal Models and Individual Fairness

NeurIPS 2024poster

In recent years, Wasserstein Distributionally Robust Optimization (DRO) has garnered substantial interest for its efficacy in data-driven decision-making under distributional uncertainty. However, limited research has explored the application of DRO to address individual fairness concerns, particula…
