贝叶斯分类是一类分类算法的总称,这类算法均以贝叶斯定理为基础,故统称为贝叶斯分类。而朴素贝叶斯(Naive Bayes)分类假设特征之间相互独立,是贝叶斯分类中最简单一种分类方法。 回顾支持向量机模型中,从训练样本集{(xi,yi)}i=1N直接学得决策函数f(x)=sign(∑i=1Nαiyi(xi⋅x)+b),对新数据实例x的预测y^直接...

3.3Multinomial Naive Bayes: MultinomialNaive Bayesnetworks, a variant of Naive Bayes networks, are better for text documents. Multinomial networks consider the frequency of words, and underlying calculations ofprobabilityare adjusted accordingly, whileNBnetworks do not consider the frequency count. ...
