Edge MAE

The implementation of Edge MAE and Edge Transformer in our paper:

Liang Yao, Jiazhen Peng, Shenggong Ji, Qiang Liu, Hongyun Cai, Feng He, and Xu Cheng. 2023. Friend Ranking in Online Games via Pre-training Edge Transformers. In Proceedings of the 46th International ACM SIGIR Conference on Research and Development in Information Retrieval (SIGIR ’23), pages 2016-2020. https://doi.org/10.1145/3539618.3591990

The repository is modified from a MAE implementation and tested on Python 3.7.

Installing requirement packages

pip install -r requirements.txt

Data

(1) Due to privacy reason, we could not provide real world data, but we prepare synthetic data in the same format in ./data.

(2) ./data/train and ./data/val are for edge classification training and validation.

(3) ./data/unlabeled are for Edge MAE pre-traininig.

How to run

1. Edge MAE pre-training

python mae_pretrain.py --model_path results/edge-mae.pt

2. Edge Transformer fine-tuning

python train_classifier.py --pretrained_model_path results/edge-mae.pt --output_model_path results/transformer2L_mae.pt

3. Train CNN (ConvKB) and Bilinear for link prediction

CNN (ConvKB)

python link_cnn.py

Bilinear

python link_bilinear.py
