WebbFeature pruning [26] is able to effectively select neurons to prune for a model, and is able to completely remove the backdoor behavior with almost no loss in model accuracy, assuming the baseline static attack. However, for a model with adversarial embedding, the full removal of the backdoor behavior simultaneously degrades the model Webb30 maj 2024 · In this paper, we provide the first effective defenses against backdoor attacks on DNNs. We implement three backdoor attacks from prior work and use them to investigate two promising defenses,...

WebbThe fine-pruning defense seeks to combine the benefits of the pruning and fine-tuning defenses. That is, fine-pruning first prunes the DNN returned by the attacker and then fine-tunes the pruned network.
