Constrained Optimization of Rank-One Functions with Indicator Variables

no code implementations31 Mar 2023 Soroosh Shafiee, Fatma Kılınç-Karzan

We then demonstrate that extended representations of sets associated with epigraphs of rank-one convex functions over constraints modeling indicator relations naturally admit such a conic representation.

Wasserstein Distributionally Robust Estimation in High Dimensions: Performance Analysis and Optimal Hyperparameter Tuning

no code implementations27 Jun 2022 Liviu Aolaritei, Soroosh Shafiee, Florian Dörfler

Wasserstein distributionally robust optimization has recently emerged as a powerful framework for robust estimation, enjoying good out-of-sample performance guarantees, well-understood regularization effects, and computationally tractable reformulations.
