模式识别课件

当预先不知道类型数目，或者用参数估计和非参数估计难以确定不同类型的类概率密度函数时，为了确定分类器的性能，可以利用聚类分析的方法。-When the pre-recognition software does not know the type of number, or parameter estimation and non-parameter estimation it is difficult to determine the different types of categories of probability density function, in order to determine the classifier performance, can make use of cluster analysis method.
