Query: Multi-view Clustering with Deep Matrix Factorization and Global Graph
  Refinement   Multi-view clustering is an important yet challenging task in machine
learning and data mining community. One popular strategy for multi-view
clustering is matrix factorization which could explore useful feature
representations at lower-dimensional space and therefore alleviate dimension
curse. However, there are two major drawbacks in the existing work: i) most
matrix factorization methods are limited to shadow depth, which leads to the
inability to fully discover the rich hidden information of original data. Few
deep matrix factorization methods provide a basis for the selection of the new
representation's dimensions of different layers. ii) the majority of current
approaches only concentrate on the view-shared information and ignore the
specific local features in different views. To tackle the above issues, we
propose a novel Multi-View Clustering method with Deep semi-NMF and Global
Graph Refinement (MVC-DMF-GGR) in this paper. Firstly, we capture new
representation matrices for each view by hierarchical decomposition, then learn
a common graph by approximating a combination of graphs which are reconstructed
from these new representations to refine the new representations in return. An
alternate algorithm with proved convergence is then developed to solve the
optimization problem and the results on six multi-view benchmarks demonstrate
the effectiveness and superiority of our proposed algorithm.
