Files in the folder

• data/: The training data

• results/: The learned embeddings of generator ane discriminator.

• code/: The source codes

• pre_train/: The pre-trained node embeddings (Note: The dimension of pre-trained node embeddings should equal n_emb)

Data

We provide three datasets: DBLP, Yelp and Aminer, The detailed description of the three datasets can refer to https://github.com/librahu/Heterogeneous-Information-Network-Datasets-for-Recommendation-and-Network-Embedding
