New HCPN-GCN method enhances Continual Graph Learning with cone prototypes

Researchers have developed HCPN-GCN, a novel approach to Continual Graph Learning (CGL) that addresses the challenge of catastrophic forgetting. This method enhances Hierarchical Prototype Networks (HPNs) by integrating Graph Convolutional Networks (GCNs) for richer graph-aware representations and employing cone-based prototypes. Experiments show HCPN-GCN significantly reduces prototype proliferation, using approximately 30 times fewer prototypes than the original HPN while maintaining high accuracy and minimal forgetting across six benchmarks.
