  17. 17. Reference • Adversarial examples in the physical world (ICLR2017 Workshop) • Ian Speech on CS231n • DeepFool: a simple and accurate method to fool deep neural networks (CVPR2016) The idea in this work is close to the orginal idea. Loop until the predicted label change. • Learning with a strong adversary (rejected by ICLR2016?) Apply the spirit of GAN to optimization. • Explaining and Harnessing Adversarial Examples (ICLR2015) Fast Gradient Sign Method • Exploring the space of adversarial images IJCNN
