保局投影(LPP)作为拉普拉斯特征映射的一种线性逼近可以较好的反映样本的流形结构，已经被广泛的应用到图像检索和图像修复中。线性鉴别分析( LDA)和局部保持投影(LPP)是其中比较经典的线性方法，LDA注重图像数据间的可分性，LPP则更关注于数据的局部关系- Locality Preserving Projection

用LDA及pca算法分析特征，选择最好的特征。-This program uses LDA and PCA to analyze features from weka arff file. The projection on PCA and LDA space visualizes the goodness of the features. If the features are good enough to be classified well they should have some ki
