Multi-View Image Clustering via Representations Fusion Method With Semi-Nonnegative Matrix Factorization

Abstract

Multi-view clustering aims to obtain the perfect clusters with a set of feature sets. Many methods learn a common agreement among views to achieve this. However, they may fail to use the specific unique feature of each view, which is important to describe the intrinsic characteristics of data. Unlike many works, we treat each view as a subset feature of data and fuse representations from those unique views to learn an integrated graph for clustering. We propose a novel representations fusion method for MVC. In this method, a regularized semi-nonnegative matrix factorization is proposed to learn the low-dimensional representation of each view, in which, a regularization term is designed to keep the neighboring structure in new low-dimensional space, and it is further updated and utilized to guide the learning process. Then the learned representations is fused to get an integrated graph for describing the image data. Finally, extensive experiments on several real image datasets show that our method achieves better performance than the state-of-the-art methods.
