CHoE: Cross-Domain Heterogeneous Graph Prompt Learning via Structure-Conditioned Experts
The article discusses a new method called CHoE for Cross-Domain Heterogeneous Graph Prompt Learning. This approach aims to enhance the performance of pre-trained models in diverse application domains. CHoE utilizes structure-conditioned experts and a prompt-based semantic fusion module to improve predictions in few-shot cross-domain scenarios.
- ▪Heterogeneous Graph Prompt Learning (HGPL) is designed to bridge the gap between pre-training models and their applications.
- ▪Current HGPL methods are limited to in-domain scenarios, which affects their performance in real-world applications.
- ▪CHoE introduces structure-conditioned experts and a routing mechanism to select compatible experts for each meta-path view.
