NOCD: Neural Overlapping Community Detection

This book demonstrates the modernized NOCD package for overlapping community detection using Graph Neural Networks.

NOCD implements the method from “Overlapping Community Detection with Graph Neural Networks” (Shchur & Gunnemann, KDD 2019), updated to use PyTorch 2.x and PyTorch Geometric.

Contents¶

• Original Demo: Training and evaluating the GCN-based community detector on the Microsoft Academic Graph dataset (reproducing the original notebook).

• Feature Transformers Demo: Using StructuralFeatures and SpectralFeatures for domain-agnostic community detection that can generalize across different types of graphs.

Installation¶

uv venv --python 3.14
uv pip install -e .
