| contents | The source detection problem in network analysis involves identifying the origins of diffusion processes, such as disease outbreaks or misinformation propagation. Traditional methods often focus on single sources, whereas real-world scenarios frequently involve multiple sources, complicating detection efforts. This study addresses the multiple-source detection (MSD) problem by integrating edge clustering algorithms into the community-based label propagation framework, effectively handling mixed-membership issues where nodes belong to multiple communities.
The proposed approach applies the automated latent space edge clustering model to a network, partitioning infected networks into edge-based clusters to identify multiple sources. Simulation studies on ADD HEALTH social network datasets demonstrate that this method achieves superior accuracy, as measured by the F1-Measure, compared to state-of-the-art clustering algorithms. The results highlight the robustness of edge clustering in accurately detecting sources, particularly in networks with complex and overlapping source regions. This work advances the applicability of clustering-based methods to MSD problems, offering improved accuracy and adaptability for real-world network analyses. |
