Abstract Multi-view clustering (MVC) methods are effective approaches to enhance clustering performance by exploiting complementary information from multiple views. One main disadvantage of most existing MVC methods is that the corresponding optimization problems are non-convex and thus local optimal solutions are usually obtained. To alleviate this issue, we propose a novel multi-view clustering method equipped with self-paced learning, which first learns the MVC model with easy examples and then progressively considers complex ones from each view. In addition, a soft weighting scheme of self-paced learning is designed to further reduce the negative impact from outliers and noises. Furthermore, to consider the importance of different views, we develop an auto-weighted technique to automatically assign weights to views. The proposed model only needs the number of clusters as input and can be easily solved by an alternating optimization paradigm. Experimental results on various benchmark data sets demonstrate the effectiveness of the proposed model.
