arxiv.orgSzegedy et al. (2014b) made an intriguing discovery: several machine learning models, including state-of-the-art neural networks, are vulnerable to adversarial examples. That is, these machine learning models misclassify examples that are only slightly different from correctly classified exam-ples drawn from the data distribution.
