Abstract:
Federated graph learning combines the power of graph learning and the data privacy-preserving properties of federated learning to provide a new solution for processing complex graph data scattered across different data sources. However, data heterogeneity may not only lead to model performance degradation but also affect the stability and convergence of model training. In addition, the local model has to consider the data security problem in the process of delivery and aggregation. Therefore, this paper proposes a Dual-branch Federated Graph Learning model with Global Graph Structure information (DFGL2GS) to cope with the statistical heterogeneity of graph data distribution and the secure interaction of graph structure information. Specifically, the local model contains two branches, Local and Global, which are used to capture personalized local features and generalized global features, respectively. The server further assists global federated graph learning modeling by capturing global graph structure information from a client generated graph that incorporates node and graph structure information. Finally, we demonstrate the effectiveness of the proposed method by conducting extensive experiments on four datasets of different domain. © 2025 Elsevier B.V.
