I have a question about the Params

[Clock966]

What do etypes_lists ，use_masks，use_masks mean？

Do you know what etypes_lists means now?

[cynricfu]

For etypes_lists, please refer to #5 .

use_masks is for solving the data leakage problem as introduced in this paper. When constructing the subgraph for generating the target nodes (e.g., user A and artist B) embeddings, we need to remove the edge between A and B to avoid leaking prediction label to the training input. So use_masks is for indicating which metapath we should be careful about to avoid this problem, that is UAU, UATAU, AUA, AUUA metapaths in LastFM.

no_masks is just indicating do not try to avoid this issue.
