Submissions for Kaggle nips 2017 adversarial image competition.

How to run Attack and Targeted Attack

1. Run cleverhans's weight downloader.
2. Copy corresponding weights to attack/fgsm_tweak_dual and targeted_attack/iter_target_class_tweak_dual.

How to run Defense

1. Download keras and h5py .whl files into defense/resnet_xception_vgg19_dual
2. Download corresponding keras pre-trained weights and put them into defense/resnet_xception_vgg19_dual/common.
3. Somehow fine-tune the above pre-trained weights with adversarial images, and put them under defense/resnet_xception_vgg19_dual.
