Pruning backdoor
Webb26 feb. 2024 · Moreover, we show that the backdoor attack induces a significant bias in neuron activation in terms of the norm of an activation map compared to its and norm. Spurred by our results, we propose the \textit { -based neuron pruning} to remove the backdoor from the backdoored DNN. Webb26 mars 2024 · Recently, deep learning has made significant inroads into the Internet of Things due to its great potential for processing big data. Backdoor attacks, which try to influence model prediction on specific inputs, have become a serious threat to deep neural network models. However, because the poisoned data used to plant a backdoor into the …

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.
