I want to change model with GAT

Questions
#1

I want to know how to use GAT in NGCF

#2

Mathematically, based on my understanding of Neural Graph Collaborative Filtering the output representation of users and items come from a (modified) GCN. You can directly replace it with a GAT.

If you have any problem in implementing this idea in DGL please feel free to follow up.

Thanks.

#3

OK Thanks, will we release the model of NGCF?

#4

We intend to add NGCF to the upcoming DGL-RecSys package but we are limited in bandwidth. If you are interested in contributing NGCF you are very welcomed. We can provide you the necessary resources if you wish.

#5

What are the recommender system models for the first DGL-RecSys version?
Thank you
