Multi-view clustering is a hot research topic due to the urgent need for analyzing a vast amount of heterogeneous data. Although many multi-view clustering methods have been developed, yet they mostly neglect the view-insufficiency issue. That is, most of the existing multi-view clustering methods assume that each individual view is sufficient for discovering the cluster structure, which is however not guaranteed in real applications. In this paper, we propose a novel multi-view clustering method termed multi-view intact space clustering (MVIC), which is able to simultaneously recover the latent intact space from multiple insufficient views and discover the cluster structure from the intact space. For each view, a view generation function is designed to map the latent intact space representation into the view representation. With the view representation given, the latent intact space can be restored by mapping back from …
