Based on the distance of Kullback-Leibler, this paper give the exact definition of the maximum Kullback-Leibler distance between two different distribution functions and prove that this one has analytic properties such as symmetry, triangle inequality which is the same as the Euclidean distance. By the definition, the maximum Kullback-Leibler distance between some conventional distributions, such as two different binomial distributions, two different normal distributions are obtianed.

Fisher criterion assumes that each sample has a unimodal,symmetric distribution for each class.However,when the training sample size is large and their distributions are multimodal or skewed,the definition of classical Fisher criterion can not correctly reflect the distribution of the data in the sample space,in that case,the sets of discriminant vectors are not optimal virtually.
Fisher准则函数的前提条件就是假设每类样本数据满足单峰高斯分布,即各类样本在模式空间的分布近似椭球状,但是当训练样本数据较多且呈多峰分布时,传统的Fisher准则函数并不能准确反映样本数据的分布,显然基于Fisher准则函数的线性判别分析得到的最优判别矢量集也不是最优的。
