This repository contains the source code for the ICML 2022 paper:
Learning from Counterfactual Links for Link Prediction
by Tong Zhao ([email protected]), Gang Liu, Daheng Wang, Wenhao Yu, and Meng Jiang.
This code package was developed and tested with Python 3.8.5, PyTorch 1.6.0, and PyG 1.6.1. All dependencies specified in the requirements.txt file. The packages can be installed by
pip install -r requirements.txt
The step of finding all the counterfactual links can be slow for the first run, please adjust the --n_workers parameter according to available processes if you are trying out different settings. The cached files for the counterfactual links that were used in our experiments can be found here, please download and put them under data/T_files/ before reproducing our experiments.
Following are the commands to reproduce our experiment results on different datasets.
