abstract = {This paper studies the vulnerability of Graph
Neural Networks against adversarial attacks by
measuring the effect of both node feature and structure
perturbations. This purpose is achieved by creating a
synthetic graph dataset containing 2708 nodes, each
with 1433 features, and 10556 edges. An instance of two
layer Graph Convolutional Network is trained on this
synthetic dataset to solve a binary classification task.
Two kinds of adversarial perturbations are introduced:
(1) node feature perturbation-the features of selected
nodes are subjected to adding some random noises; (2)
graph structure perturbation-addition or deletion of
edges. The model is then evaluated on the clean test set
and then reevaluated after applying the adversarial
perturbations. Results show a significant decrease in
classification accuracy following the introduction of
such attacks, thus emphasizing how vulnerable GNNs
are to adversarial manipulation. This framework
constitutes a valuable approach toward studying
adversarial robustness within graph-based models and
points toward more resilient architectures for practical
applications with GNNs.},
