基于半监督典型相关分析的多视图维数约简
Semi-supervised canonical correlation analysis based multi-view dimensionality reduction
摘要
Abstract
In order to efficiently reduce dimensionality in multi-view semi-supervised scenarios,this paper proposed semi-su-pervised canonical correlation analysis methods which used nonnegative low-rank graph to propagate labels.Global linear neigh-borhoods captured by nonnegative low-rank graph could utilize information from both direct and reachable indirect neighbors to preserve the global cluster structures,while the low-rank property retained a compressed representation of the graph.After esti-mating label information of unlabeled samples by label propagation algorithm,it constructed soft label matrices of all samples and probabilistic within-class scatter matrices in each view.Then,by maximizing the correlations between samples of the same class from cross views and minimizing within-class variations in the low-dimensional feature space of each view simultaneously, it enhanced discriminative power of features.Experimental results demonstrate that the proposed methods can achieve better recognition performances and robustness than existing related methods and are effective multi-view dimensionality reduction methods.关键词
