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 features 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 u...

偏最小二乘分析(Partial Least Squares,PLS)模型的鲁棒性使其成为回归分析和维数压缩的有力工具之一。由于传统的非线性迭代偏最小二乘分析(Nonlinear Iterative PLS,NI-PALS)的解不确定,实际中经常用奇异值分解的迭代算法实现[1]。另一方面,采用基于正交约束的非迭代PLS(Orth
