HePa: Heterogeneous Graph Prompting for All-Level Classification Tasks
AAAI 2025technical
Heterogeneous graphs, which are common in real-world downstream tasks, have recently sparked a wave of research interest. The performance of end-to-end heterogeneous graph neural networks (HGNNs) greatly relies on supervised training for specific tasks. To reduce the labeling cost, the "pretrain-fin…
