Beyond Homophily: Spectrum-Based Graph Pre-Training and Cluster-Augmented Prompt Tuning
Graph pre-training and prompt tuning provide an effective route to label-efficient node classification by learning transferable backbones and adapting them with lightweight prompts. However, existing pre-train-and-prompt pipelines often generalize poorly across graphs with diverse homophily due to two fundamental limit...
