CopulaGNN

This repo provides a PyTorch implementation for the CopulaGNN models as described in the following paper:

CopulaGNN: Towards Integrating Representational and Correlational Roles of Graphs in Graph Neural Networks

Jiaqi Ma, Bo Chang, Xuefei Zhang, and Qiaozhu Mei. ICLR 2021.

Requirements

Most dependency packages are included in environment.yml. Run conda torch_env create -f environment.yml to install the required packages.

In addition, one also needs to install PyTorch-Geometric following the official installation instructions.

The code is tested with the following PyTorch-Geometric version.

torch-scatter==2.0.5
torch-sparse==0.6.7
torch-cluster==1.5.7
torch-geometric==1.6.1

Run the code

Example: python main.py --lr 0.001 --hidden_size 16 --dataset wiki-squirrel --model_type regcgcn.
