Inductive learning on Reddit

[sunisfighting]

Hi, @rusty1s , thanks for your really great job and wonderful codes!!! I am recently doing some jobs about Graph Representation Learning and I am working on Reddit dataset. It seems you deal with the dataset in the way of semi-supervised transductive node classification just like for Cora ,Citeseer, and Pubmed? I am a little confused about if we should split the whole dataset into training/validation/testing graph and then use metis to partition them seperately in the setting of inductive learning? I am looking forward to receiving your reply!! Thanks very much!!

Thanks for your interest. It is correct that we do not treat Reddit as inductive (I found out that some works do while others do not). If you want to apply GAS on Reddit in an inductive learning scenario, you can simply do so via

train_data = data.subgraph(data.train_mask)

and train via train_data rather than data.
