Directed Graph Contrastive Learning
Paper | Poster | Supplementary
The PyTorch implementation of Directed Graph Contrastive Learning (DiGCL).
In this paper, we present the first contrastive learning framework for learning directed graph representation.

Requirements
Our project is developed using Python 3.7, PyTorch 1.7.0 with CUDA10.2. We recommend you to use anaconda for dependency configuration.
First create an anaconda environment called DiGCL by
conda create -n DiGCL python=3.7
conda activate DiGCLThen, you need to install torch manually to fit in with your server environment (e.g. CUDA version). For the torch and torchvision used in my project, run
conda install pytorch==1.7.0 torchvision==0.6.0 cudatoolkit=10.2 -c pytorchBesides, torch-scatter and torch-sparse are required for dealing with sparse graph. For these two packages, please follow their official instruction torch-scatter and torch-sparse.
Other requirements can be set up through:
cd DiGCL
pip install -e .Usage
cd code
python train_digcl.py --gpu_id 0 --dataset cora_ml --curr-type log
python train_digcl.py --gpu_id 0 --dataset citeseerThe --dataset argument can be one of [cora_ml, citeseer] and the --curr-type argument can be one of [linear, log, exp, fixed].
