torchadver is a Pytorch tool box for generating adversarial images. The basic adversarial attack are implemented. Such as FSGM, I-FGSM, MI-FGSM, M-DI-FGSM, C&W .etc.
The brief attack process is shown below. More detailed process introduction you can refer to ./examples/toturial.py.
Non-targeted attack
from torchadver.attacker.iterative_gradient_attack import FGM_L2, I_FGM_L2, MI_FGM_L2, M_DI_FGM_L2
mean = [0.5, 0.5, 0.5]
std = [0.5, 0.5, 0.5]
# images normalized by mean and std
images, labels = ...
model = ...
# use mean and std to determine effective range of pixel of image in channels.
attacker = FGM_L2(model, loss_fn=nn.CrossEntropyLoss(),
mean=mean, std=std,
max_norm=4.0, # L2 norm bound
random_init=True)
# for non-targeted attack
adv_images = attacker.attack(images, labels) # or adv_images = attacker.attack(images)Targeted attack
