gtrick: Bag of Tricks for Graph Neural Networks.

gtrick is an easy-to-use Python package that collects tricks for graph neural networks. It tests and provides powerful tricks to boost your models' performance.

Trick is all you need! (English Document | 中文介绍)

Library Highlights

• Easy-to-use: All it takes is to add a few lines of code to apply a powerful trick, with as few changes to existing code as possible.
• Verified Trick: All tricks implemented in gtrick are tested on our selected datasets. Only the tricks indeed improving a model's performance can be collected by gtrick.
• Backend Free: We provide all tricks both in DGL and PyG. Whatever graph learning library you use, feel free to try it.

Installation

Note: This is a developmental release.

pip install gtrick

Quick Start

It is very easy to get started with gtrick. You can enhance your GNN model with only a few lines of code.

For more detailed examples, see Example in Trick.

Trick

Trick	Example	Task	Reference
VirtualNode	DGL PyG	graph	OGB Graph Property Prediction Examples
FLAG	DGL PyG	node* graph	Robust Optimization as Data Augmentation for Large-scale Graphs
Fingerprint	DGL PyG	molecular graph*	Extended-Connectivity Fingerprints
Random Feature	DGL PyG	graph*	Random Features Strengthen Graph Neural Networks
Label Propagation	DGL PyG	node*	Learning from Labeled and Unlabeled Data with Label Propagation
Correct & Smooth	DGL PyG	node*	Combining Label Propagation And Simple Models Out-performs Graph Neural Networks
Common Neighbors	DGL PyG	link*	Link Prediction with Structural Information
Resource Allocation	DGL PyG	link*	Link Prediction with Structural Information
Adamic Adar	DGL PyG	link*	Link Prediction with Structural Information
Anchor Distance	DGL PyG	link*	Link Prediction with Structural Information

We have tested all these tricks on selected datasets, you can find the benchmark in PyG Benchmark and DGL Benchmark.

Contributing

Please let me know if you encounter a bug or have any suggestions by filing an issue.

All contributions for bug fixes, new tricks, and better examples are welcome.

There are also some tricks I'm planning to add, feel free to implement one of them for gtrick:

• SCR
• GSAT
• Edge Proposal Set
