Robust Upper Bounds for Adversarial Training

1 code implementation17 Dec 2021 Dimitris Bertsimas, Xavier Boix, Kimberly Villalobos Carballo, Dick den Hertog

We introduce a new approach to adversarial training by minimizing an upper bound of the adversarial loss that is based on a holistic expansion of the network instead of separate bounds for each layer.

Mixed-Integer Optimization with Constraint Learning

1 code implementation4 Nov 2021 Donato Maragno, Holly Wiberg, Dimitris Bertsimas, S. Ilker Birbil, Dick den Hertog, Adejuyigbe Fajemisin

The case studies illustrate the framework's ability to generate high-quality prescriptions as well as the value added by the trust region, the use of ensembles to control model robustness, the consideration of multiple machine learning methods, and the inclusion of multiple learned constraints.

Optimization with Constraint Learning: A Framework and Survey

1 code implementation5 Oct 2021 Adejuyigbe Fajemisin, Donato Maragno, Dick den Hertog

Many real-life optimization problems frequently contain one or more constraints or objectives for which there are no explicit formulas.
