通过双层解耦与一致性学习,提升多视图聚类的特征判别性与簇内紧凑性。
Multi-view Clustering via Bi-level Decoupling and Consistency Learning
- 双层解耦分离特征与聚类空间,增强判别能力。
- 在5个基准数据集上优于当前最优方法。
- 适合需要高精度聚类的多源数据场景。
多视图聚类在分析多视图数据潜在模式方面表现出色。通过学习多视图特征间的一致性与互补性可提升聚类性能,但面向聚类的表征学习常被忽视。本文提出一种新型双层解耦与一致性学习框架(BDCL),进一步探索多视图数据的有效表征,以增强聚类中特征的类间判别性与类内紧凑性。该框架包含三个模块:1)多视图实例学习模块通过重建自编码器与对比学习对齐一致信息,同时保留各视图的私有特征;2)特征与聚类的双层解耦机制增强特征空间与聚类空间的判别性;3)一致性学习模块将样本及其邻居的不同视图视为正例对,学习其聚类分配的一致性,并压缩类内空间。在五个基准数据集上的实验结果表明,该方法优于当前最优方法。代码已开源于 https://github.com/LouisDong95/BDCL。
原文摘要 · Abstract (English)
Multi-view clustering has shown to be an effective method for analyzing underlying patterns in multi-view data. The performance of clustering can be improved by learning the consistency and complementarity between multi-view features, however, cluster-oriented representation learning is often overlooked. In this paper, we propose a novel Bi-level Decoupling and Consistency Learning framework (BDCL) to further explore the effective representation for multi-view data to enhance inter-cluster discriminability and intra-cluster compactness of features in multi-view clustering. Our framework comprises three modules: 1) The multi-view instance learning module aligns the consistent information while preserving the private features between views through reconstruction autoencoder and contrastive learning. 2) The bi-level decoupling of features and clusters enhances the discriminability of feature space and cluster space. 3) The consistency learning module treats the different views of the sample and their neighbors as positive pairs, learns the consistency of their clustering assignments, and further compresses the intra-cluster space. Experimental results on five benchmark datasets demonstrate the superiority of the proposed method compared with the SOTA methods. Our code is published on https://github.com/LouisDong95/BDCL.
