Bounding the Expected Robustness of Graph Neural Networks Subject to Node Feature Attacks

1 code implementation27 Apr 2024 Yassine Abbahaddou, Sofiane Ennadir, Johannes F. Lutzeyer, Michalis Vazirgiannis, Henrik Boström

In this work, we theoretically define the concept of expected robustness in the context of attributed graphs and relate it to the classical definition of adversarial robustness in the graph representation learning literature.

A Simple and Yet Fairly Effective Defense for Graph Neural Networks

1 code implementation21 Feb 2024 Sofiane Ennadir, Yassine Abbahaddou, Johannes F. Lutzeyer, Michalis Vazirgiannis, Henrik Boström

Successful combinations of our NoisyGNN approach with existing defense techniques demonstrate even further improved adversarial defense results.
