基于最大边界准则的稀疏局部嵌入特征提取方法
Sparse local embedding feature extraction method based on maximum margin criterion
摘要
Abstract
The local linear embedding(LLE) was unable to take advantage of the discrimination information of the samples and the maximum margin criterion (MMC) had a weak performance on the nonlinear data.Therefore this paper proposed a feature extraction method called sparse local embedding based on maximum margin criterion (SLE/MMC).With the preservation of local nearest neighbor premise,firstly,the similar samples were gathering together as much as possible in the intrinsic graph.Secondly,the samples of different classes were as far as possible from each other in the penalty graph.Finally,it used the elastic net regression to obtain an optimal sparse projection matrix.In order to avoid the "small sample size" problem,it constructed the objective function by MMC.The experiment results on ORL,Yale and UMIST show that,compared with other methods (PCA,LLE and MMC),SLE/MMC has a higher recognition rate,indicating that this method is more efficient in feature extraction.关键词
