Robust Empirical Risk Minimization with Tolerance
Not on the map. Why?
Abstract (arXiv)
Developing simple, sample-efficient learning algorithms for robust classification is a pressing issue in today's tech-dominated world, and current theoretical techniques requiring exponential sample complexity and complicated improper learning rules fall far from answering the need. In this work we study the fundamental paradigm of (robust) textitempirical risk minimization (RERM), a simple process in which the learner outputs any hypothesis minimizing its training error. RERM famously fails to robustly learn VC classes (Montasser et al., 2019a), a bound we show extends even to `nice' settings such as (bounded) halfspaces. As such, we study a recent relaxation of the robust model called textittolerant robust learning (Ashtiani et al., 2022) where the output classifier is compared to the best achievable error over slightly larger perturbation sets. We show that under geometric niceness conditions, a natural tolerant variant of RERM is indeed sufficient for γ-tolerant robust learning VC classes over ℝd, and requires only tildeOleft( fracVC(H)dlog fracDγδε2right) samples for robustness regions of (maximum) diameter D.
