新型防御方法KCES增强图神经网络安全性

研究人员开发了一种名为Kernel-Complexity Edge Sanitization (KCES) 的新型无训练方法,用于防御图神经网络 (GNN) 免受结构攻击。KCES利用图Gram矩阵导出的度量——图核复杂度 (GKC),为每条边分配一个影响分数。通过修剪具有高KC分数的边(这些边通常是对抗性扰动的目标),KCES可以在无需重新训练模型的情况下减轻这些攻击的影响。该方法计算效率高、可扩展性强,并可与现有防御措施集成,在大量实验中展示了比基线方法持续的性能提升。 AI

影响 增强了图神经网络对抗对抗性攻击的鲁棒性,可能提高了其在敏感应用中的可靠性。
