Hi LuckyJinging,
Thanks for your question! Since our dataset is homogeneous graph which only contains one relation type, we do not use the inter-relation AGG in CARE-CNN. We mainly want to compare with the RL-based neighbor selector in CARE-GNN, as the RL-based neighbor selector has the potential to alleviate the inconsistency problem.
Hope I have solved you question!π
Thanks for your quick responseπ! May I know if you adopted the early stopping strategy in the other baselines and what were their training epochs?
hi LuckyJinging,
If I remember correctly, I tested the early stopping for other baselines, and found it may make the second-stage training overfitting for some baselines, so I unified the maximum training epochs. DCI is a thought for self-supervised training, I think you can also try the early stopping and set a better setting for your experiments.
Thank you!π
Thank you! I also want to know if you adopted the early stopping strategy in joint training algorithms for fairness?
Both joint training algorithms and decoupled training algorithms use the cross-entropy to optimize the encoder and classifier, and they run in the same setting for a fair comparison. The difference between joint training and decoupled training is that the latter one adopts SSL to pre-train the graph encoder for a better parameter initialization to serve the second-stage end2end training.π
Thanks for your patiently reply~! β€
No problem! Inspired by DCI, we have developed another SSL objective ClusterSCL. https://github.com/wyl7/ClusterSCL
Feel free to email me, if you have any question!π
Thank you! They are excellent jobs and I will try to follow your work!
Hi,
I try to read the experimental setup in your paper. I am wondering how you did evaluate the performance of CARE-GNN designed for multi-relation graphs, on the wiki dataset?
Thank you very much,
