This is the official repo for the paper FLAG: Adversarial Data Augmentation for Graph Neural Networks.

TL;DR: FLAG augments node features to generalize GNNs on both node and graph classification tasks.

• Simple, adding just a dozen lines of code
• General, directly applied to any GNN baseline
• Versatile, working on both node and graph classification tasks
• Scalable, minimum extra memory overhead, working on the original infrastructure

Other baselines including GCN, GraphSAGE, GAT, GIN, MLP, etc. are available here.

To view the empirical performance of FLAG, please visit the Open Graph Benchmark Node an Graph classification leaderboards.
