Distributionally Robust Learning with Weakly Convex Losses: Convergence Rates and Finite-Sample Guarantees

Landi Zhu, Mert Gürbüzbalaban, Andrzej Ruszczyński

We consider a distributionally robust stochastic optimization problem and formulate it as a stochastic two-level composition optimization problem with the use of the mean--semidevi…

A Stochastic Subgradient Method for Distributionally Robust Non-Convex Learning

Mert Gürbüzbalaban, Andrzej Ruszczyński, Landi Zhu

We consider a distributionally robust formulation of stochastic optimization problems arising in statistical learning, where robustness is with respect to uncertainty in the underl…
