Quarantine: Sparsity Can Uncover the Trojan Attack Trigger for Free. (arXiv:2205.11819v1 [cs.LG])

Trojan attacks threaten deep neural networks (DNNs) by poisoning them to
behave normally on most samples, yet to produce manipulated results for inputs
attached with a particular trigger. Several works attempt to detect whether a
given DNN has been injected with a specific trigger during the training. In a
parallel line of research, the lottery ticket hypothesis reveals the existence
of sparse subnetworks which are capable of reaching competitive performance as
the dense network after independent training. Connecting these two …
