Federated Graph Neural Network
Federated Graph Neural Networks (FedGNNs) combine the power of graph neural networks (GNNs) for analyzing relational data with federated learning (FL) for privacy-preserving distributed training. Current research focuses on addressing challenges like data heterogeneity across clients, improving model accuracy and convergence speed, and mitigating vulnerabilities to backdoor and label inference attacks, often employing techniques like asynchronous computations and differential privacy within various GNN architectures. This field is significant for enabling collaborative machine learning on sensitive graph data in domains like healthcare and transportation, while also advancing our understanding of distributed learning and its security implications.
