Query: Adversarial examples are useful too!   Deep learning has come a long way and has enjoyed an unprecedented success.
Despite high accuracy, however, deep models are brittle and are easily fooled
by imperceptible adversarial perturbations. In contrast to common
inference-time attacks, Backdoor (\aka Trojan) attacks target the training
phase of model construction, and are extremely difficult to combat since a) the
model behaves normally on a pristine testing set and b) the augmented
perturbations can be minute and may only affect few training samples. Here, I
propose a new method to tell whether a model has been subject to a backdoor
attack. The idea is to generate adversarial examples, targeted or untargeted,
using conventional attacks such as FGSM and then feed them back to the
classifier. By computing the statistics (here simply mean maps) of the images
in different categories and comparing them with the statistics of a reference
model, it is possible to visually locate the perturbed regions and unveil the
attack.
