  • 摘要: 多视图聚类通过以无监督的方式探索多视图的语义信息而得到广泛的关注. 针对现有的方法忽略了表示的多样性学习和视图之间冗余信息等方面的缺陷, 提出一种基于冗余消除的深度多视图聚类增强融合网络 REMVC.首先引入特征聚合模块, 学习样本之间的全局结构关系用于生成一致的表示; 其次引入冗余消除模块减少潜在空间特征之间的信息相关性, 提高了嵌入表示的辨别能力; 最后引入公共表示的正则化约束模块, 通过最大化公共表示每个维度上的方差并最小化不同维度之间的协方差, 探索多视图实例特征的互补信息. 所提网络联合优化了表示学习、冗余消除和正则化约束模块, 以提高聚类性能. 在 7 个广泛使用的数据集上进行实验的结果表明, REMVC 在准确度、归一化互信息和纯度上优于参与对比的 7 种多视图聚类方法.

     

    Abstract: Multi-view clustering has received much attention by exploring the semantic information of multiple views in an unsupervised manner. To address the shortcomings of existing methods that overlook the learning of representation diversity and redundant information between views, a novel enhanced fusion network through redundancy elimination for deep multi view clustering (REMVC) is proposed. Firstly, a feature aggregation module is introduced to learn the global structural relationships between samples for generating consistent representations. Secondly, a redundancy elimination module is introduced to reduce the information correlation between potential spatial features and improve the discriminative ability of embedded representations. Finally, a regularization constraint module for common representation is introduced to explore the complementary information of multi-view instance features by maximizing the variance on each dimension of the common representation and minimizing the covariance between different dimensions. The proposed network jointly optimizes the representation learning, redundancy elimination, and regularization constraint modules to improve clustering performance. The results of experiments on 7 widely used datasets show that REMVC outperforms the 7 multi-view clustering methods involved in comparison in terms of accuracy, normalized mutual information, and purity.
