Graph Neural Networks for Source Detection: A Review and Benchmark Study
A new study published on arXiv explores the effectiveness of Graph Neural Networks (GNNs) for source detection in epidemic processes on contact networks. Researchers systematically reviewed existing GNN-based methods and conducted a benchmark study comparing four GNN architectures against traditional and MLP-based baselines. The experiments demonstrated that GNNs significantly outperform other tested methods across various network topologies, challenging initial skepticism and highlighting their remarkable effectiveness for this task. The study also released all code and data to ensure reproducibility and proposed epidemic source detection as a valuable benchmark for evaluating GNN architectures. AI
