Fisher z转换 The Fisher Z-Transformation is a way to transform thesampling distributionofPearson’s r (i.e. the correlation coefficient)so that it becomesnormally distributed. The “z” in Fisher Z stands for az-score. The formula to transform r to a z-score is: z’ = .5[ln(1+r) ...

对于一个两类分类器,可以计算g(x)=g2(x)-g1(x)。若g(x)≥0,则r(x)=2,相应于决策区R2。若g(x)<0,则r(x)=1,相应于决策区R1。这一结果可写成 式中sgn(Z)是符号函数,在Z≥0时等于1,在Z<0时等于-1。这样一个两类线性分类器具有图中的形式。
已知,则目标函数可转换为: 其中, 为张量样本在n模展开条件下的表示,m取值范围为[1,M]; 将公式(2)表示成类似MPCA的目标函数形式: 其中, 表示U (n) 的转置,tr(*)表示矩阵的迹,S B (n) 为张量样本在n模展开下的局部类间散度矩阵,S W (n) 为张量样本在n模展开下的局部类内散度矩阵; 通过求解公式(...
