This is the PyG implementation for WSDM'23 paper: S2GAE: Self-Supervised Graph Autoencoders Are Generalizable Learners with Graph Masking

S2GAE is a generalized self-supervised graph representation learning method, which achieves competitive or better performance than existing state-of-the-art methods on different types of tasks including node classification, link prediction, graph classification, and molecular property prediction.

<h2>Installation</h2>

The required packages can be installed by running pip install -r requirements.txt.

<h2>Datasets</h2> The datasets used in our paper can be automatically downlowad. <h2>Quick Start</h2> For quick start, you could try:

Node classification (Cora, CiteSeer, and PubMed)

python s2gae_nc_acc.py --dataset `Cora`

Link prediction (ogbl-ddi, ogbl-collab, and ogbl-ppa)

python s2gae_large_lp.py --dataset "ogbl-ddi"

Graph classification
