摘要
Abstract
Non-iterative PLS based on orthogonal constraints(ONIPLS) can extract PLS features rapidly and effectively,while the features maybe correlative. PLS based on Uncorrelated Score Constraints(UCSNIPLS) can extract uncorrelated fcatures which make image recognition more effectively and steadily.2DPLS can extract features from image matrices, which can solve the small sample problems at the same time.While the classical class label encoding is too simple, fuzzy k-near neighbors' method is employed in order to make use of the sample distributions. Then improved algorithms of PLS and 2DPLS based on sample class label encoding are given. The results of experiments on ORL face database show that the improved algorithms presented are better than classical PLS,and can extract discriminant features efficiently.关键词
