对有类别监督的数据进行先行判别分析用于降维
数据为结构体类型,返回数据也是降维后的结构体类型。如(a.X a.y)a.X是带有类别的数据,a.y是类别信息-Synopsis:
model = lda(data)
model = lda(data,new_dim)

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 recognit

LDA是一种监督学习的降维技术,也就是说它的数据集的每个样本是有类别输出的,这点和PCA不同。PCA是不考虑样本类别输出的无监督降维技术。
