Directional Graph Networks

Implementation of Directional Graph Networks in PyTorch and DGL.

Overview

We provide the implementation of the Directional Graph Networks (DGN) in PyTorch and DGL frameworks, along with scripts for running real-world benchmarks. The repository is organised as follows:

• models contains:
  • pytorch contains the various GNN models implemented in PyTorch: the implementation of the aggregators, the scalers, the DGN layer and the directional aggregation matrix (eigen_agg).
  • dgl contains the DGN model implemented via the DGL library: aggregators, scalers, and DGN layer.
  • layers.py contains general NN layers used by the various models
• realworld_benchmark contains various scripts from Benchmarking GNNs and Open Graph Benchmark to download the real-world benchmarks and train the DGN on them. In realworld_benchmark/README.md we provide instructions for runnning the experiments.
