LW-GNN

An offical PyTorch implementation of "Label-Wise Graph Convolutional Network for Heterophilic Graphs".

Overview

  • ./models: This directory contains the proposed LW-GCN.
  • ./dataset.py: This is the code to load datasets.
  • ./data: The datasets are stored here.
  • ./scripts: It contains the scripts to reproduce the major reuslts of our paper.
  • ./train_BI.py: The program to train LW-GCN that incorporate the label-wise graph convolution and GCNII with model selection.
  • ./train_DIS.py: The program to train LW-GCN\G that removes the model selection module.
  • ./log: We provide our training log at ./log as a reference to reproduce the results in the paper

Requirements

python>=3.7
torch==1.7.1
torch-geometric==1.7.2
cuda=11.0

Install Packages

conda install pytorch==1.7.1 torchvision==0.8.2 torchaudio==0.7.2 cudatoolkit=11.0 -c pytorch 
pip install --no-index torch-scatter -f https://pytorch-geometric.com/whl/torch-1.7.1+cu110.html
pip install --no-index torch-sparse -f https://pytorch-geometric.com/whl/torch-1.7.1+cu110.html
pip install --no-index torch-cluster -f https://pytorch-geometric.com/whl/torch-1.7.1+cu110.html
pip install --no-index torch-spline-conv -f https://pytorch-geometric.com/whl/torch-1.7.1+cu110.html
pip install torch-geometric==1.7.1

Experiments

To reproduce the performance in the paper, you can run the bash files in the .\scripts. For example, to get results on cora datasets

# Run the LW-GCN on all datasets
bash train_BI.sh

# Run the LW-GCN\G that does not deploy model selection on all heterophilic graphs
bash train_DIS.sh

You can also check the our recorded log in .\log to help reproduce the experiments we conducted.
