Chainer Graph CNN

This is a Chainer implementation of Defferrard et al., "Convolutional Neural Networks on Graphs with Fast Localized Spectral Filtering", NIPS 2016. (https://arxiv.org/abs/1606.09375)

Disclaimer: PFN provides no warranty or support for this implementation. Use it at your own risk. See license for details.

This is not the original author's implementation. This implementation was based on https://github.com/mdeff/cnn_graph.

Usage

# Trains a GraphCNN on MNIST
$ python tools/train.py -c configs/default.json -o results -e 100 -g 0

Prerequisites

pip install -r requirements.txt

This implementation has been tested with the following versions.

python 2.7.6
chainer (1.19.0)
nose (1.3.7)
numpy (1.11.3)
scikit-learn (0.18.1)
scipy (0.18.1)

It may work with other versions; not tested.
