MSGNN: Novel spectral GNN architecture for signed and directed networks

Researchers have developed MSGNN, a novel spectral graph neural network architecture designed for signed and directed networks. This new model utilizes a magnetic signed Laplacian matrix, which generalizes existing Laplacian matrices for signed and directed graphs. Experiments demonstrate MSGNN's effectiveness in node clustering and link prediction tasks, outperforming existing methods on datasets incorporating both signed and directional information. AI
