We thank the reviewers for their insightful feedback, and we appreciate the opportunity to improve our paper. We will1 address typos and notational inconsistencies in the updated version.2 Response to Reviewer 1:3 We would like to emphasize that Theorem 1 is the most important contribution of our paper due to its generality.4 By considering the set of all possible classifiers, it provides lower bounds on adversarial robustness for any pair of5 class-conditional distributions. As we show in our experimental results in Section 6, we are able to obtain lower bounds6 for arbitrary real-world datasets by constructing the empirical distribution for these. In our estimation, these results7 serve to provide theoretical validation for adversarial training for low perturbation budgets as well as to highlight the8 gap to optimality for higher budgets.9
