大佬,打扰一下,我是需要验证个人的一些算法与防御算法的结合对于图上攻击的效果,由于时间问题,只使用了提供好meta、nettack结构,meta效果还挺正常,但是nettack好像没有什么效果,而且1.0 -5.0是表示扰动程度吗?我跑了一下,好像没有什么攻击效果啊,是我使用的问题吗,如果有时间,望您回一下,打扰了

nettack是targeted attack,会对target node影响很大,但对模型整体效果影响不大。

你可以看看这个文件test_nettack.py.

能在问一下,目前像meta-attack一样改变图结构就能产生很好的攻击效果的,还有什么其他的方法吗,我对这方面不是很懂,只是现在需要一些对抗攻击方面的应用,目前看到一篇综述论文,描述了一些攻击手段,当前试了meta-attack net-attack,像topology、DICE能否和meta-attack有类似的效果?
