朴素贝叶斯分类的工作过程如下: (1)  每个数据样本用一个n维特征向量X= {x1,x2,……,xn}表示,分别描述对n个属性A1,A2,……,An样本的n个度量。 (2) 假定有m个类C1,C2,…,Cm,给定一个未知的数据样本X(即没有类标号),分类器将预测X属于具有最高后验概率(条件X下)的类。也就是说,朴素贝叶斯分类将未知的样本分配给类Ci(1≤i≤m)当且仅当P(Ci|X)> P(Cj|X),对任意的j=1,2,…,m,j≠i。这样,最大化P(Ci|X)。其P(Ci|X)最大的类Ci称为最大后验假定。根据贝叶斯定理 相关下载链接:[url=//download.csdn.net/download/k573338063/4543853?utm_source=bbsseo]//download.csdn.net/download/k573338063/4543853?utm_source=bbsseo[/url]
