贝叶斯分类算法是统计学的一种分类方法，它是一类利用概率统计知识进行分类的算法。在许多场合，朴素贝叶斯(Naï ve Bayes，NB)分类算法可以与决策树和神经网络分类算法相媲美，该算法能运用到大型数据库中，而且方法简单、分类准确率高、速度快。-Bayesian classification algorithm is a statistical classification method, which is a kind of knowledge to classify the use of probabilistic algorithms. In many cases, Naive Bayes (Naï ve Bayes, NB) classification algorithm with decision trees and neural network classification algorithm is comparable, the algorithm can be applied to large s, and the method is simple, accurate classification rate of speed.
