New bagging method offers exponential improvement in adversarial robustness

Researchers have developed a new method for learning predictors that are robust to adversarial examples at test time. This approach achieves sample complexity linear in the VC dimension, an exponential improvement over previous bounds. The algorithm combines bagging (bootstrap aggregation) with robust empirical risk minimization (RERM), outputting the majority vote of RERMs computed on bootstrap samples. A complementary lower bound indicates that this linear sample complexity is unavoidable for learners in this model. AI
