LDA 线性判别分析 有监督 分类

将高维的模式样本投影到最佳鉴别矢量空间,以达到抽取分类信息和压缩特征空间维数的效果,投影后保证模式样本在新的子空间有最大的类间距离和最小的类内距离,即模式在该空间中有最佳的可分离性,与PCA区别:LDA考虑分类标签,属于有监督分类。 (Linear discriminant analysis (LDA) is a generalization of Fisher s linear discriminant, a method used in statistics, pattern recognition and machine learning to find a linear combination of features that characterizes or separates two or more classes of objects or events. The resulting combination may be used as a linear classifier, or, more commonly, for dimensionality reduction before later classification.)
