thanks for your message. The feature attacks of nettack are only meant for binary node attributes. You can still run nettack with only structure perturbations, though.
Best,

hi，I am honored to read your paper, and I would like to use your ideas in my own data set. But it didn't work very well. I think it's because of my data set. In my data set,the node feature is a number between -1 and 1 which is different from yours dataset. And when i set perturb_features = True,the program will always select the same feature of the same node to attack.which is this:
Starting attack
Attack node with ID 4544 using structure and feature perturbations
Attacking the node indirectly via 5 influencer nodes
Performing 100 perturbations
Influencer nodes: [3463 1829 3198 1837 4399]
...1/100 perturbations ...
Edge perturbation: [1837 1079]
...2/100 perturbations ...
Edge perturbation: [1837 1824]
...3/100 perturbations ...
Feature perturbation: [1829 35]
...4/100 perturbations ...
Feature perturbation: [1829 35]
...5/100 perturbations ...
Feature perturbation: [1829 35]
...6/100 perturbations ...
as you can see :in 3,4,5 and after,the network always select feature [1829,35] to attack. What do you think the problem is and how do I change the code?Looking forward to your reply!
