Convex--Concave Quadratic Spectral Filtering for Graph Neural Networks

Researchers propose DCQ-GNN, a spectral graph neural network using adaptive convex-concave quadratic filters to improve frequency selectivity without high computational costs. The model demonstrates competitive performance on both homophilic and heterophilic graphs while maintaining robustness under structural perturbations.
