New GNN defense uses self-supervised purifier against adversarial attacks

Researchers have developed a novel self-supervised adversarial purification framework for Graph Neural Networks (GNNs). This new method separates the task of robustness from classification by using a dedicated purifier, GPR-GAE, which is a graph auto-encoder trained with a self-supervised strategy. The GPR-GAE utilizes multiple Generalized PageRank filters to capture diverse structural representations, enabling effective purification and robust defense against adversarial attacks on graph data.
