摘要:

多视图数据中的丰富信息以及不同视图之间的互补信息通常有利于各种任务,例如,聚类、分类、去噪。多视点子空间聚类是基于多视点数据是从一个潜在子空间中产生的这一事实。为了恢复潜在的子空间结构,最近已经见证了稀疏和/或低秩子空间聚类的成功。尽管一些最先进的子空间聚类方法可以在数值上处理多视图数据,通过同时探索视图内所有可能的成对相关性,但高阶统计量往往被忽略,而高阶统计量只能通过同时利用所有视图来捕获。因此,多视图数据的聚类性能受到损害。针对这一问题,提出了一种基于三阶张量空间\textit{t-product}的多视图聚类方法。基于循环卷积运算,多视图数据可以有效地表示由\textit{t-linear}组合稀疏和低秩惩罚使用“自我表达”。我们在人脸、物体、数字图像和文本数据上的大量实验结果表明,所提出的方法在许多标准方面都优于现有的方法。

英文摘要:

The plenty information from multiple views data as well as the complementary information among different views are usually beneficial to various tasks, e.g., clustering, classification, de-noising. Multi-view subspace clustering is based on the fact that the multi-view data are generated from a latent subspace. To recover the underlying subspace structure, the success of the sparse and/or low-rank subspace clustering has been witnessed recently. Despite some state-of-the-art subspace clustering approaches can numerically handle multi-view data, by simultaneously exploring all possible pairwise correlation within views, the high order statistics is often disregarded which can only be captured by simultaneously utilizing all views. As a consequence, the clustering performance for multi-view data is compromised. To address this issue, in this paper, a novel multi-view clustering method is proposed by using \textit{t-product} in third-order tensor space. Based on the circular convolution operation, multi-view data can be effectively represented by a \textit{t-linear} combination with sparse and low-rank penalty using "self-expressiveness". Our extensive experimental results on facial, object, digits image and text data demonstrate that the proposed method outperforms the state-of-the-art methods in terms of many criteria.
