Spectral Designed Graph Convolutions

Codes of "Bridging the Gap Between Spectral and Spatial Domains in Graph Neural Networks" paper.

Requirements

These libraries versions are not stricly needed. But these are the configurations in our test machine.

• Python==3.6.5
• tensorflow-gpu==1.15.0
• numpy==1.17.4
• networkx==2.4
• scipy==1.3.1
• matplotlib==3.1.2
• pickle==4.0

Usage

Run the scripts directly. All parameters are defined in corresponding script. In Pubmed and PPI dataset, since the eigen decomposition takes quite a long time because of the dimension of given graph, we write the eigenvectors into file in first run. For later run, the code directly read already calculated eigenvectors from file.

Transductive Setting Problems

python cora_multirun.py
python citeseer_multirun.py
python pubmed_multirun.py

Inductive Setting Problems

python ppi_singlerun.py
python protein_nodelabel.py
python enzymes_nodelabel.py
python enzymes_allfeats.py
