Analyzing the Robustness of Deep Learning Against Adversarial Examples
Jun Zhao · 2018
Recent studies have shown the vulnerability of many deep learning algorithms to adversarial examples, which an attacker obtains by adding subtle perturbation to benign inputs in order to cause misbehavior of deep learning. For instance, an attacker can add carefully selected noise to a panda image so that the resulting image is still a panda to a human being but is predicted as a gibbon by the deep learning algorithm. As a first step to propose effective defense mechanisms against such adversarial examples, we analyze the robustness of deep learning against adversarial examples. Specifically, we prove a strict lower bound for the minimum ℓpdistortion of a data point to obtain an adversarial example.
