Machine learning models are vulnerable to adversarial examples formed by applying small carefully chosen perturbations to inputs that cause unexpected classification errors. In this paper, we perform experiments on various adversarial example generation approaches with multiple deep convolutional neural networks including Residual Networks, the best performing models on ImageNet Large-Scale Visual Recognition Challenge 2015. We compare the adversarial example generation techniques with respect to the quality of the produced images, and measure the robustness of the tested machine learning models to adversarial examples. Finally, we conduct large-scale experiments on cross-model adversarial portability. We find that adversarial examples are mostly transferable across similar network topologies, and we demonstrate that better machine learning models are less vulnerable to adversarial examples.

通过利用深度卷积神经网络生成对抗性样本，然后比较不同的生成技术在产生图像质量和测试机器学习模型鲁棒性方面的差异，最后在跨模型对抗迁移上进行了大规模实验，研究结果表明对抗性样本在相似的网络拓扑间是可传递的，并且更好的机器学习模型更不容易受到对抗性样本的攻击。

准确性和鲁棒性是否相关？
