Computing Estimators of Dantzig Selector type via Column and Constraint Generation
Rahul Mazumder, Stephen Wright, Andrew Zheng
We consider a class of linear-programming based estimators in reconstructing a sparse signal from linear measurements. Specific formulations of the reconstruction problem considere…
Convergence and Margin of Adversarial Training on Separable Data
Zachary Charles, Shashank Rajput, Stephen Wright +1
Adversarial training is a technique for training robust machine learning models. To encourage robustness, it iteratively computes adversarial examples for the model, and then re-tr…
Bilinear Bandits with Low-rank Structure
Kwang-Sung Jun, Rebecca Willett, Stephen Wright +1
We introduce the bilinear bandit problem with low-rank structure in which an action takes the form of a pair of arms from two different entity types, and the reward is a bilinear f…
