基于监督学习的一种非线性数据降维方法，可以很好地将低维特征从其所在的高维流形中提取出来，用于数据分类。(A nonlinear data dimension reduction based on supervised learning method, is a good way to the lower dimensional feature extracted from its place of higher dimensional manifold, used for data classification.)

瑞丽衰落和莱斯衰落的对比 瑞利衰落（Rayleigh Fading）：在无线通信信道中，由于信号进行多径传播达到接收点处的场强来自不同传播的路径，各条路径延时时间是不同的，而各个方向分量波的叠加，又产生了驻波场强，从而形成信号快衰落称为瑞利衰落。瑞利衰落属于小尺度的衰落效应，它总是叠加于如阴影、衰减等大尺度衰落效应上。(rice fading and rayleigh fading)
