Certifiably Robust Graph Contrastive Learning. (arXiv:2310.03312v1 [cs.CR])
cs.CR updates on arXiv.org arxiv.org
Graph Contrastive Learning (GCL) has emerged as a popular unsupervised graph
representation learning method. However, it has been shown that GCL is
vulnerable to adversarial attacks on both the graph structure and node
attributes. Although empirical approaches have been proposed to enhance the
robustness of GCL, the certifiable robustness of GCL is still remain
unexplored. In this paper, we develop the first certifiably robust framework in
GCL. Specifically, we first propose a unified criteria to evaluate and certify
the robustness …
