It's All in the Mix: Wasserstein Machine Learning with Mixed Features
Problem definition: The recent advent of data-driven and end-to-end decision-making across
different areas of operations management has led to an ever closer integration of prediction …

Distributionally and adversarially robust logistic regression via intersecting Wasserstein balls
Adversarially robust optimization (ARO) has become the de facto standard for training models
to defend against adversarial attacks during testing. However, despite their robustness, …

Convex maximization via adjustable robust optimization
Maximizing a convex function over convex constraints is an NP-hard problem in general.
We prove that such a problem can be reformulated as an adjustable robust optimization (ARO) …

Differential Privacy via Distributionally Robust Optimization
In recent years, differential privacy has emerged as the de facto standard for sharing statistics
of datasets while limiting the disclosure of private information about the involved individuals…

Wasserstein logistic regression with mixed features
Recent work has leveraged the popular distributionally robust optimization paradigm to
combat overfitting in classical logistic regression. While the resulting classification scheme …

A reformulation-linearization technique for optimization over simplices
We study non-convex optimization problems over simplices. We show that for a large class
of objective functions, the convex approximation obtained from the Reformulation-…

Using column generation to solve extensions to the Markowitz model
We introduce a solution scheme for portfolio optimization problems with cardinality constraints.
Typical portfolio optimization problems are extensions of the classical Markowitz mean–…

Can Synthetic Data Reduce Conservatism of Distributionally Robust Adversarial Training?
When the inputs of a machine learning model are subject to adversarial attacks, standard
stationarity assumptions on the training and test sets are violated, typically making empirical …
