New nonlinear Laplacian operator enhances graph neural networks for signed-directed data

Researchers have developed a new non-linear Laplacian operator, termed NLSD, specifically designed for signed-directed graphs. This operator extends existing concepts for signed and directed graphs by calculating node-specific potentials and leveraging message-passing techniques only across edges where potential discrepancies align with the edge's direction. The proposed NLSD-GNN framework, built upon this operator, demonstrates superior performance in node classification and link prediction tasks across various datasets, effectively integrating both signed and directional information.
