Disagreement-Aware Subgraph Federated Learning via Uncertainty-Guided Local-Global Alignment

FedDUA is proposed, a novel disagreement-aware and uncertainty-guided framework for subgraph FL that first models cross-client semantic disagreement via a lightweight semantic anchor graph and derives adaptive aggregation weights for reliable global federated knowledge.

Disagreement-Aware Subgraph Federated Learning via Uncertainty-Guided Local-Global Alignment

Subgraph federated learning (subgraph FL) enables collaborative graph neural network training without sharing raw graph data, but suffers from severe Non-IID distributions and structural fragmentation. In such settings, Non-IID distributions induce pronounced client specialization, where each client excels in a subset...
