Does LightGCN support to include the node features? #8656

It seems to me that LightGCN creates node embeddings without considering the node features |

Yes, that's correct. This is how LightGCN is designed. It shouldn't be too hard though to add node features to it, e.g., via concatenation with embeddings. |

I only have node features on the items, does it make sense if I introduce a Linear layer to convert item node features to the same dimension as the user node embedding, and concat them together for lightgcn? |
