Hi @Leirunlin. Thank you for your interest in this repo.
- Thank you for pointing out that. I followed the implementation from here and adjusted the code from DeepRobust. In my experiments, multiplying
lr
withnum_budgets
improves its attack performance and is even better than that of DeepRobust. So I just kept it as a better solution. - Agreed.
PGDAttack
is sensitive tolr
and one should carefully tunebase_lr
to obtain better performance. I can provide some empirical guidance if this is needed. - AFAIK,
MinMax
is less used in literature as a comparison method. I think current implementation ofPGDAttack
is sufficient, which is also able to perform poisoning attacks by passing training set nodes asvictim_nodes
. Nevertheless, I can integrateMinMax
into this repo as well. - Yes, this repo is designed to be completely compatible with PyG in terms of data, layers, and models. You can definitely use any PyG models as surrogate models to perform attacks as long as they are implemented in a form that accepts
x, edge_index, edge_weight
as input. For now, most attacks exceptMetattack
andNettack
should support most PyG models other than GCN.

Hi. Thanks for your detailed answer.
In my experiments, multiplying lr
with num_budgets
also improves the performance of CE loss, especially in the poison setting, but is relatively less useful for CW loss. Unfortunately, I didn't find literature discussing this phenomenon. It would be helpful if any advice about the choice of base_lr
is provided.
Again, thanks for your efforts on this repo. I'm really looking forward to the released version.

I'll dig into that and report back. The first released version would be coming soon. BTW, the master branch is always available :D
