Multi-view clustering has received substantial research because of its ability to discover heterogeneous information in the data. The weight distribution of each view of data has always been difficult problem in multi-view clustering. In order to solve this problem and improve computational efficiency at the same time, in this paper, Reweighted multi-view clustering with tissue-like P system (RMVCP) algorithm is proposed. RMVCP performs a two-step operation on data. Firstly, each similarity matrix is constructed by self-representation method, and each view is fused to obtain a unified similarity matrix and the updated similarity matrix of each view. Subsequently, the updated similarity matrix of each view obtained in the first step is taken as the input, and then the view fusion operation is carried out to obtain the final similarity matrix. At the same time, Constrained Laplacian Rank (CLR) is applied to the final matrix, so that the clustering result is directly obtained without additional clustering steps. In addition, in order to improve the computational efficiency of the RMVCP algorithm, the algorithm is embedded in the framework of the tissue-like P system, and the computational efficiency can be improved through the computational parallelism of the tissue-like P system. Finally, experiments verify that the effectiveness of the RMVCP algorithm is better than existing state-of-the-art algorithms.
多视图聚类因其能够发现数据中的异构信息而受到广泛研究。在多视图聚类中,数据各视图的权重分布一直是一个难题。为了解决这个问题并同时提高计算效率,本文提出了一种基于组织样 P 系统的重加权多视图聚类(RMVCP)算法。RMVCP 对数据执行两步操作。首先,通过自表示方法构建每个相似性矩阵,并融合各视图以获得统一的相似性矩阵和各视图的更新相似性矩阵。然后,将第一步中获得的各视图的更新相似性矩阵作为输入,然后进行视图融合操作,以获得最终的相似性矩阵。同时,将约束拉普拉斯秩(CLR)应用于最终矩阵,从而无需额外的聚类步骤即可直接获得聚类结果。此外,为了提高 RMVCP 算法的计算效率,将该算法嵌入到组织样 P 系统的框架中,通过组织样 P 系统的计算并行性来提高计算效率。最后,实验验证了 RMVCP 算法的有效性优于现有的最先进算法。
