PyTorch implementation of PE-GNN

(Architecture of a naive GCN versus that of PE-GNN, enhanced with a positional encoder.)

This is the official repository for the AISTATS 2023 paper Positional Encoder Graph Neural Networks for Geographic Data (Konstantin Klemmer, Nathan Safir, Daniel B. Neill).

Structure

The source code for PE-GNN (using PyTorch) can be found in the src folder. Its built on PyTorch Geometric (ICLR-W, 2019) and Space2Vec (ICLR, 2020).

We also provide an interactive example notebook to test PE-GNN via Google Colab
