Multi-view clustering excels by leveraging complementary multi-perspective data, yet current methods still face the following challenges: 1) How to balance local and global representations across views; 2) How to mitigate the degradation of representation quality caused by enforcing consistency across multi-view data; 3) Many contrastive learning methods align cross-view representations but neglect clustering information, leading to false negative pairs. To address these issues, this paper proposes a framework for Progressive Feature Contrastive and Self-Weighted Neighbor-masked Fusion (PCSNFMVC). First, autoencoders extract view-specific features, where contrastive learning enforces local consistency by aligning low-level cross-view features. Then, these features are adaptively fused through a self-weighting mechanism to generate global representations, while high-level view features are projected to maximize consistency with the global representation, achieving local-global balance. Finally, a neighborhood-masked contrastive learning method is employed to distinguish high-similarity negative samples during the embedding aggregation process, effectively addressing the previously mentioned issue of false negative pairs. Experimental results on seven datasets demonstrate the superiority of this method.

摘要

Multi-view clustering excels by leveraging complementary multi-perspective data, yet current methods still face the following challenges: 1) How to balance local and global representations across views; 2) How to mitigate the degradation of representation quality caused by enforcing consistency across multi-view data; 3) Many contrastive learning methods align cross-view representations but neglect clustering information, leading to false negative pairs. To address these issues, this paper proposes a framework for Progressive Feature Contrastive and Self-Weighted Neighbor-masked Fusion (PCSNFMVC). First, autoencoders extract view-specific features, where contrastive learning enforces local consistency by aligning low-level cross-view features. Then, these features are adaptively fused through a self-weighting mechanism to generate global representations, while high-level view features are projected to maximize consistency with the global representation, achieving local-global balance. Finally, a neighborhood-masked contrastive learning method is employed to distinguish high-similarity negative samples during the embedding aggregation process, effectively addressing the previously mentioned issue of false negative pairs. Experimental results on seven datasets demonstrate the superiority of this method.
