Embedding Graph Auto-Encoder for Graph Clustering

This repository is our implementation of

Hongyuan Zhang, Pei Li, Rui Zhang, and Xuelong Li, "Embedding Graph Auto-Encoder for Graph Clustering," IEEE Transactions on Neural Networks and Learning Systems, 2022.

The core idea of EGAE is to design a GNN to find an ideal space for the relaxed k-means on graph data. We prove that the relaxed k-means will obtain a precise clustering result under some strong assumptions. So we attempt to use GNNs to map the data into an ideal space that satisfies the strong assumptions.

How to Run EGAE

python run.py

Requirements

pytorch >= 1.3.1

scipy 1.3.1

scikit-learn 0.21.3

numpy 1.16.5

Remark

• model.py: An efficient implementation which can be used when datasets are not too large.
• sparse_model.py: It is a sparse implementation of EGAE for large scale datasets, e.g., PubMed.
