Risk Guarantees for End-to-End Prediction and Optimization Processes

no code implementations30 Dec 2020 Nam Ho-Nguyen, Fatma Kılınç-Karzan

While it is usually believed that good prediction performance in estimating the parameters will result in good subsequent optimization performance, formal theoretical guarantees on this are notably lacking.

Adversarial Classification via Distributional Robustness with Wasserstein Ambiguity

no code implementations28 May 2020 Nam Ho-Nguyen, Stephen J. Wright

Inspired by this observation, we show that, for a certain class of distributions, the only stationary point of the regularized ramp loss minimization problem is the global minimizer.
