Query: Towards Robust Fine-grained Recognition by Maximal Separation of
  Discriminative Features   Adversarial attacks have been widely studied for general classification
tasks, but remain unexplored in the context of fine-grained recognition, where
the inter-class similarities facilitate the attacker's task. In this paper, we
identify the proximity of the latent representations of different classes in
fine-grained recognition networks as a key factor to the success of adversarial
attacks. We therefore introduce an attention-based regularization mechanism
that maximally separates the discriminative latent features of different
classes while minimizing the contribution of the non-discriminative regions to
the final class prediction. As evidenced by our experiments, this allows us to
significantly improve robustness to adversarial attacks, to the point of
matching or even surpassing that of adversarial training, but without requiring
access to adversarial samples.
