Paper, Poster and Presentation

Please check our arXiv version here for the full paper with supplementary. We also provide our poster in this repo. Our oral presentation video at AAAI-2022 can be found on YouTube, for both the brief introduction and the full presentation.

Requirement

rdkit
pytorch 1.10.0
pytorch_geometric 2.0.2

Dataset Preparation

TUDataset and MNISTSuperpixel

$ python download_dataset.py

Semi-supervised Learning

There are many settings for semi-supervised learning, you can change to other experiments by changing the --exp flag. The node attribute augmentation is by default disabled, you can enable it by setting the --add_mask flag to True.

$ python main.py --exp=joint_cl_exp --semi_split=10 --dataset=MUTAG --save=joint_cl_exp --epochs=30 --batch_size=128 --lr=0.01

You can use the give script to run multiple experiments, you may need to adjust the hyper-parameter like batch_size to make it runnable on your devices.

$ sh run.sh

Unsupervised Learning

Run

$ sh un_exp.sh

Transfer Learning

Prepare the Dataset

$ cd transfer
$ wget http://snap.stanford.edu/gnn-pretrain/data/chem_dataset.zip
$ unzip chem_dataset.zip
$ rm -rf dataset/*/processed

Run the Fine-tuning Experiments

$ sh run_chem.sh
