PyTorch Implementation of Graph U-Nets

Created by Hongyang Gao @ Iowa State University, and Shuiwang Ji @ Texas A&M University.

About

PyTorch implementation of Graph U-Nets. Check http://proceedings.mlr.press/v97/gao19a/gao19a.pdf for more information.

Methods

Graph Pooling Layer

Graph Unpooling Layer

Graph U-Net

Installation

Type

./run_GNN.sh DATA FOLD GPU

to run on dataset using fold number (1-10).

You can run

./run_GNN.sh DD 0 0

to run on DD dataset with 10-fold cross validation on GPU #0.

Code

The detail implementation of Graph U-Net is in src/utils/ops.py.

Datasets

Check the "data/README.md" for the format.
