Webb7 sep. 2024 · Based on a prior observation that backdoors exploit spare capacity in the neural network [ 18 ], we then propose and evaluate pruning as a natural defense. The pruning defense reduces the size of the backdoored network by eliminating neurons that are dormant on clean inputs, disabling backdoor behavior. Webbför 2 dagar sedan · When a deep learning-based model is attacked by backdoor attacks, it behaves normally for clean inputs, whereas outputs unexpected results for inputs with specific triggers. This causes serious threats to deep learning-based applications. Many backdoor detection... Webb27 okt. 2024 · Based on these observations, we propose a novel model repairing method, termed Adversarial Neuron Pruning (ANP), which prunes some sensitive neurons to purify the injected backdoor. Experiments show, even with only an extremely small amount of clean data (e.g., 1 causing obvious performance degradation. READ FULL TEXT … fort walters beach florida
