Graph Convolutional Matrix Completion

Tensorflow based implemention of Graph Convolutional Matrix Completion for recommender systems, based on our paper:

Rianne van den Berg, Thomas N. Kipf, Max Welling, Graph Convolutional Matrix Completion (2017)

Installation

python setup.py install

Requirements

• Python 2.7
• TensorFlow (1.4)
• pandas

Usage

To reproduce the experiments mentioned in the paper you can run the following commands:

Douban

python train.py -d douban --accum stack -do 0.7 -nleft -nb 2 -e 200 --features --feat_hidden 64 --testing 

Flixster

python train.py -d flixster --accum stack -do 0.7 -nleft -nb 2 -e 200 --features --feat_hidden 64 --testing

Yahoo Music

python train.py -d yahoo_music --accum stack -do 0.7 -nleft -nb 2 -e 200 --features --feat_hidden 64 --testing

Movielens 100K on official split with features

python train.py -d ml_100k --accum stack -do 0.7 -nleft -nb 2 -e 1000 --features --feat_hidden 10 --testing

Movielens 100K on official split without features

python train.py -d ml_100k --accum stack -do 0.7 -nleft -nb 2 -e 1000 --testing

Movielens 1M

python train.py -d ml_1m --data_seed 1234 --accum sum -do 0.7 -nsym -nb 2 -e 3500 --testing

Movielens 10M

python train_mini_batch.py -d ml_10m --data_seed 1234 --accum stack -do 0.3 -nsym -nb 4 -e 20 --testing 

Note: 10M dataset training does not fit on GPU memory (12 Gb), therefore this script uses a naive version of mini-batching. Script can take up to 24h to finish.
