基于动态锚点与质量感知混合专家的多视图聚类OA
Multi-view clustering with dynamic anchors and a quality-aware mixture of experts
多视图聚类旨在挖掘不同视图间的共识性与互补性,但现有方法面临两大瓶颈:一是全局拓扑建模依赖预定义相似度与固定邻域,难以适应复杂分布;二是样本级视图质量差异显著,静态加权策略难以刻画细粒度可靠性变化,尤其在数据缺失场景下鲁棒性不足.为此,提出基于动态锚点与质量感知混合专家的多视图聚类框架(DAMC-MoE).首先,利用可学习的动态锚点机制代替传统预定义相似度,实现拓扑结构建模与特征表征学习的端到端深度耦合;在此基础上,引入质量感知混合专家模块,利用样本级完整度与信噪比生成质量令牌,引导门控机制执行自适应路由,实现了从传统视图级加权向样本级细粒度感知融合的范式转变;最后,构建三层对比学习机制,从视图间、视图内及局部-全局层面联合强化语义对齐.在五个基准数据集上与 11个先进算法的全面对比实验中,DAMC-MoE 展现出优越的聚类性能.Friedman检验结果进一步显示,DAMC-MoE在三项聚类评价指标上的平均排名均显著高于对比方法.
Multi-view clustering aims to exploit the consensus and complementarity across different views,yet existing methods face two major bottlenecks:first,global topology modeling relies on predefined similarity measures and fixed neighborhoods,making it difficult to adapt to complex data distributions;second,sample-level view quality varies significantly,and static weighting strategies fail to characterize fine-grained reliability changes,particularly lacking robustness in missing data scenarios.To this end,we propose a multi-view clustering framework based on Dynamic Anchors and quality-aware Mixture-of-Experts(DAMC-MoE).First,a learnable dynamic anchor mechanism replaces traditional predefined similarity measures,achieving end-to-end deep coupling between topological structure modeling and feature representation learning.Building on this,a quality-aware mixture-of-experts module is introduced,which generates quality tokens from sample-level completeness and signal-to-noise ratio to guide the gating mechanism for adaptive routing,realizing a paradigm shift from conventional view-level weighting to sample-level fine-grained perceptual fusion.Finally,a three-level contrastive learning mechanism is constructed to jointly reinforce semantic alignment from inter-view,intra-view,and local-global perspectives.In comprehensive comparative experiments on 5 benchmark datasets against 11 state-of-the-art algorithms,DAMC-MoE demonstrates superior clustering performance.Friedman test results further indicate that DAMC-MoE achieves significantly higher average rankings across three clustering evaluation metrics compared to all baseline methods.
