Selective Cross-View Topology for Deep Incomplete Multi-View Clustering

Abstract

Incomplete multi-view clustering has gained significant attention due to the prevalence of incomplete multi-view data in real-world scenarios. However, existing methods often overlook the critical role of inter-view relationships. In unsupervised settings, selectively leveraging cross-view topological relationships can effectively guide view completion and representation learning. To address this challenge, we propose a novel framework called Selective Cross-View Topology Incomplete Multi-View Clustering (SCVT). Our approach constructs a view topology graph using the Optimal Transport (OT) distance between view. This graph helps identify neighboring views for those with missing data, enabling the inference of topological relationships and accurate completion of missing samples. Additionally, we introduce the Max View Graph Contrastive Alignment module to facilitate information transfer and alignment across neighboring views. Furthermore, we propose the View Graph Weighted Intra-View Contrastive Learning module, which enhances representation learning by pulling representations of samples within the same cluster closer, while applying varying degrees of enhancement across different views based on the view graph. Our method achieves state-of-the-art performance on seven benchmark datasets, significantly outperforming existing methods for incomplete multi-view clustering and demonstrating its effectiveness.
