用可学习的文本代理动态捕捉用户兴趣,精准发现个性化聚类。

Multi-modal Dynamic Proxy Learning for Personalized Multiple Clustering

  • 通过自适应融合机制动态建模跨模态特征交互。
  • 在多个基准上优于现有方法,显著提升聚类精度。
  • 适合需要个性化聚类分析的应用场景。

多聚类旨在从不同视角发现多样化的潜在结构,但现有方法生成全部聚类而无法识别用户兴趣,需人工筛选。当前多模态方法存在语义僵化问题:预定义候选词无法适配数据集特定概念,固定融合策略忽略特征交互演化。为此,我们提出Multi-DProxy,一种基于可学习文本代理的多模态动态代理学习框架,通过跨模态对齐实现自适应融合。该框架引入:1)门控跨模态融合,自适应建模特征交互以生成判别性联合表示;2)双约束代理优化,用户兴趣约束确保与领域概念语义一致,概念约束通过困难样本挖掘增强聚类区分度;3)动态候选管理,通过迭代聚类反馈精炼文本代理。因此,Multi-DProxy不仅能有效通过代理捕捉用户兴趣,还能更精准识别相关聚类。大量实验表明,在多个多聚类基准上达到领先性能,显著优于现有方法。

原文摘要 · Abstract (English)

Multiple clustering aims to discover diverse latent structures from different perspectives, yet existing methods generate exhaustive clusterings without discerning user interest, necessitating laborious manual screening. Current multi-modal solutions suffer from static semantic rigidity: predefined candidate words fail to adapt to dataset-specific concepts, and fixed fusion strategies ignore evolving feature interactions. To overcome these limitations, we propose Multi-DProxy, a novel multi-modal dynamic proxy learning framework that leverages cross-modal alignment through learnable textual proxies. Multi-DProxy introduces 1) gated cross-modal fusion that synthesizes discriminative joint representations by adaptively modeling feature interactions. 2) dual-constraint proxy optimization where user interest constraints enforce semantic consistency with domain concepts while concept constraints employ hard example mining to enhance cluster discrimination. 3) dynamic candidate management that refines textual proxies through iterative clustering feedback. Therefore, Multi-DProxy not only effectively captures a user's interest through proxies but also enables the identification of relevant clusterings with greater precision. Extensive experiments demonstrate state-of-the-art performance with significant improvements over existing methods across a broad set of multi-clustering benchmarks.
