摘　　要：针对流形学习算法——局部保持映射存在的参数选择及不能进行非线性特征提取的问题,提出一种基于核的监督流形学习算法.该算法作为局部保持映射算法的改进算法用样本类标识信息指导建立局部最近邻图,并在建立局部最近邻图使用无参数的相似度量.利用核方法来解决局部保持映射算法在处理线性不可分问题上的局限性问题.在两个常用数据库上验证本文算法的可行性和有效性.A kernel based supervised manifold learning method is presented to solve the problems on parameter selection with locality preserving projection and inability in nonlinear feature extraction, which is unresolved by the currently proposed manifold learning algorithm. The proposed algorithm is an improvement of locality preserving projection （LPP）. The nearest neighbor graph is created with the class label information of the samples, and nonparametric similarity measure is used. The kernel method is used to solve the limitation the proposed algorithm are problem of the nonlinear separability for LPP. The feasibility and effectivity of testified on two databases.
