Title
Graph-regularized multi-view semantic subspace learning
Abstract
Many real-world datasets are represented by multiple features or modalities which often provide compatible and complementary information to each other. In order to obtain a good data representation that synthesizes multiple features, researchers have proposed different multi-view subspace learning algorithms. Although label information has been exploited for guiding multi-view subspace learning, previous approaches did not well capture the underlying semantic structure in data. In this paper, we propose a new multi-view subspace learning algorithm called multi-view semantic learning (MvSL). MvSL learns a nonnegative latent space and tries to capture the semantic structure of data by a novel graph embedding framework, where an affinity graph characterizing intra-class compactness and a penalty graph characterizing inter-class separability are generally defined. The intuition is to let intra-class items be near each other while keeping inter-class items away from each other in the learned common subspace across multiple views. We explore three specific definitions of the graphs and compare them analytically and empirically. To properly assess nearest neighbors in the multi-view context, we develop a multiple kernel learning method for obtaining an optimal kernel combination from multiple features. In addition, we encourage each latent dimension to be associated with a subset of views via sparseness constraints. In this way, MvSL is able to capture flexible conceptual patterns hidden in multi-view features. Experiments on three real-world datasets demonstrate the effectiveness of MvSL.
