- Abstract:
This paper presents a novel method, DCOM-GNN, designed to optimize deep clustering in graph neural networks (GNNs). The approach targets improving the clustering performance in graph-based learning by incorporating a clustering loss into the GNN framework. The authors focus on enhancing the quality of learned representations while minimizing intra-cluster distances and maximizing inter-cluster distances, leading to more efficient and accurate graph clustering. The method demonstrates its effectiveness through various experimental results on benchmark datasets, showing improvements over existing clustering techniques in GNNs.

- Authors: Haoran Yang, et al.
- Conference: NeurIPS 2024 (Accepted)
- Abstract:
This paper proposes a unified framework to address the challenge of integrating homophily (similarity between neighboring nodes) and heterophily (dissimilarity between neighboring nodes) in spectral graph neural networks (SGNNs). The authors introduce Triple Filter Ensembles, a novel technique that combines multiple filter types to account for both homophilic and heterophilic structures in a graph. The method allows SGNNs to adaptively learn from graphs with varying node relationships, improving model robustness and generalization across diverse graph datasets.
