Hard No-Box Adversarial Attack on Skeleton-Based Human Action Recognition with Skeleton-Motion-Informed Gradient. (arXiv:2308.05681v1 [cs.CV])
cs.LG updates on arXiv.org arxiv.org
Recently, methods for skeleton-based human activity recognition have been
shown to be vulnerable to adversarial attacks. However, these attack methods
require either the full knowledge of the victim (i.e. white-box attacks),
access to training data (i.e. transfer-based attacks) or frequent model queries
(i.e. black-box attacks). All their requirements are highly restrictive,
raising the question of how detrimental the vulnerability is. In this paper, we
show that the vulnerability indeed exists. To this end, we consider a new
attack task: the …
