Dual Alignment Self-Supervised Incomplete Multi-View Subspace Clustering Network

Incomplete multi-view clustering has attracted much attention in decade years. To date, most of the remarkable achievements, however, exploit shallow models to learn shared feature representations based on incomplete views. Although some deep learning methods have been proposed to solve this issue, the existing ones still have the following problems: 1) The consistency between views is ignored, which will have serious negative impacts on incomplete multi-view learning. 2) The learned features do not have sufficient cluster-friendliness, that is, the tightness within clusters and the repulsiveness between clusters are not fully considered. To tackle the above shortcomings, we propose a Dual Alignment Self-supervised Incomplete Multi-view Subspace Clustering network (DASIMSC) in this paper. Specifically, the manifold alignment constraint and consistency alignment constraint are integrated with the autoencoder to preserve the compact inherent local structure within the view and the consistency semantics between incomplete views, respectively. Moreover, a self-expression layer coupled with a spectral clustering module is designed to naturally separate different types of data, leveraging the current clustering results to supervise subspace learning, which excludes inter-cluster. Experimental results on several datasets show that our algorithm outperforms all compared state-of-the-arts.
