Twin Reciprocal Completion for Incomplete Multi-View Clustering

Abstract

Incomplete multi-view clustering is an important and challenging task, which has attracted significant attention in recent years. The key objective of incomplete multi-view clustering is to excavate the underlying avaliable consistency of multi-view data, so as to enable the effective reconstruction of missing views for clustering. In this paper, we introduce a completion framework that deeply explores the underlying consistency and effectively completes the missing views. Following that, we propose a novel Twin Reciprocal Completion for Incomplete multi-view clustering, termed TRC-IMC for short. To be specific, TRC-IMC jointly conducts the Completion in Feature space (CF) and the Completion in Subspace (CS) to reciprocally complete the data with missing views. The underlying high-order consistency of multi-view data can be fully explored in both the feature space and subspace to guide the completion process of missing views. Extensive experiments are conducted on eight real-world multi-view datasets, and experimental results indicate the promising performance of our method, compared to several state-of-the-arts.
