- Title: Generative Partial Multi-View Clustering
- Authors: Qianqian Wang, Zhengming Ding, Zhiqiang Tao, Quanxue Gao, Yun Fu
- Abstract summary: We propose a generative partial multi-view clustering model, named as GP-MVC, to address the incomplete multi-view problem.
First, multi-view encoder networks are trained to learn common low-dimensional representations, followed by a clustering layer to capture the consistent cluster structure across multiple views.
Second, view-specific generative adversarial networks are developed to generate the missing data of one view conditioning on the shared representation given by other views.

- Abstract: Nowadays, with the rapid development of data collection sources and feature
extraction methods, multi-view data are getting easy to obtain and have
received increasing research attention in recent years, among which, multi-view
clustering (MVC) forms a mainstream research direction and is widely used in
data analysis. However, existing MVC methods mainly assume that each sample
appears in all the views, without considering the incomplete view case due to
data corruption, sensor failure, equipment malfunction, etc. In this study, we
design and build a generative partial multi-view clustering model, named as
GP-MVC, to address the incomplete multi-view problem by explicitly generating
the data of missing views. The main idea of GP-MVC lies at two-fold. First,
multi-view encoder networks are trained to learn common low-dimensional
representations, followed by a clustering layer to capture the consistent
cluster structure across multiple views. Second, view-specific generative
adversarial networks are developed to generate the missing data of one view
conditioning on the shared representation given by other views. These two steps
could be promoted mutually, where learning common representations facilitates
data imputation and the generated data could further explores the view
consistency. Moreover, an weighted adaptive fusion scheme is implemented to
exploit the complementary information among different views. Experimental
results on four benchmark datasets are provided to show the effectiveness of
the proposed GP-MVC over the state-of-the-art methods.

We propose a novel incomplete multi-view clustering network, called Cognitive Deep Incomplete Multi-view Clustering Network (CDIMC-net)
It captures the high-level features and local structure of each view by incorporating the view-specific deep encoders and graph embedding strategy into a framework.
Based on the human cognition, i.e., learning from easy to hard, it introduces a self-paced strategy to select the most confident samples for model training.

This study presents a new approach called Sufficient Multi-View Clustering (SUMVC) that examines the multi-view clustering framework from an information-theoretic standpoint.
Firstly, we develop a simple and reliable multi-view clustering method SCMVC that employs variational analysis to generate consistent information.
