A Survey on Multi-View Clustering

With the fast development of information technology, especially the popularization of internet, multi-view learning becomes more and more popular in machine learning and data mining fields. As we all know that, multi-view semi-supervised learning, such as co-training, co-regularization has gained considerable attentions. Although recently, multi-view clustering (MVC) has developed rapidly, there are not a survey or review to summarize and analyze the current progress. Therefore, this paper sums up the common strategies of combining multiple views and based on that we proposed a novel taxonomy of the MVC approaches. We also discussed the relationships between MVC and multi-view representation, ensemble clustering, multi-task clustering, multi-view supervised and multi-view semi-supervised learning. Several representative real-world applications are elaborated. To promote the further development of MVC, we pointed out several open problems that are worth exploring in the future.
