Backdoor attacks pose a new threat to NLP models. A standard strategy to construct poisoned data in backdoor attacks is to insert triggers (e.g., rare words) into selected sentences and alter the original label to a target label. This strategy comes with a severe flaw of being easily detected from both the trigger and the label ...

WebThere are two major types of backdoor attacks, i.e., poison-label attacks and clean-label attacks. The difference between the two is the poisoning of their parameters. In poison-label attacks, the training examples and labels are both poisoned, while in clean-label attacks, only the training examples are poisoned [ 18 ]. WebWe recommend to use pre-preprocessed data or pre-backdoored model for rapid testing since the files are large. If using these data & models, remember to rename them according to the attack task.

Web2.2 Previous Backdoor Attacks We ﬁrst review BadNets [1], the most common backdoor attack method. The network is trained for an image classiﬁcation task f : X!C, in which Xis an input image domain and C= fc 1;c 2;:::;c Mg is a set of Mtarget classes. A clean training set S= f(x i;y i)ji= 1;Ngis provided, in which x i 2Xis a training image and y Webremain untouched. Backdoor attacks share a close connection to noisy label attacks, in that during a backdoor attack, the feature can only be altered insigniﬁcantly to put the trigger in disguise, which makes the corrupted feature (e.g. images with the trigger) highly similar to the uncorrupted ones.
