Graph Convolutional Matrix Completion

Paper link: https://arxiv.org/abs/1706.02263 Author's code: https://github.com/riannevdberg/gc-mc

The implementation does not handle side-channel features and mini-epoching and thus achieves slightly worse performance when using node features.

Dependencies

• PyTorch 1.2+
• pandas
• torchtext 0.9+ (if using user and item contents as node features)
• spacy (if using user and item contents as node features)
  • You will also need to run python -m spacy download en_core_web_sm

Data

Supported datasets: ml-100k, ml-1m, ml-10m

How to run

Train with full-graph

ml-100k, no feature

python3 train.py --data_name=ml-100k --use_one_hot_fea --gcn_agg_accum=stack

Results: RMSE=0.9088 (0.910 reported)

ml-100k, with feature

python3 train.py --data_name=ml-100k --gcn_agg_accum=stack

Results: RMSE=0.9448 (0.905 reported)

ml-1m, no feature

python3 train.py --data_name=ml-1m --gcn_agg_accum=sum --use_one_hot_fea

Results: RMSE=0.8377 (0.832 reported)

ml-10m, no feature

python3 train.py --data_name=ml-10m --gcn_agg_accum=stack --gcn_dropout=0.3 \
                                 --train_lr=0.001 --train_min_lr=0.0001 --train_max_iter=15000 \

Train with minibatch on a single GPU

ml-100k, no feature

python3 train_sampling.py --data_name=ml-100k \
