2. 贝叶斯定理(Bayes' theorem) 在现实生活中,经常存在这样的情况:我们可以很容易直接得出P(A|B),而P(B|A)则很难直接得出,但我们更关心P(B|A),贝叶斯定理就为我们打通从P(A|B)获得P(B|A)的道路。 贝叶斯定理的简单推导: 已知P(A|B)=P(AB)P(B),因此P(AB)=P(B)P(A|B) 同理可得:P(AB)=...
Nave Bayes classifier is one of the most popular data mining algorithms for classification, which provides an optimal way to predict the class of an unknown example. We tested the performance of our proposed algorithm by employing KDD99 benchmark network intrusion detection dataset, and the ...

The NBC is a probabilistic classifier based on applying Bayes’ theorem with strong (naive) independence assumptions. In a nutshell, an NBC assigns inputs into one of thekclasses {C1,C2, ..., Ck} based on some properties (features) of the inputs. NBCs have applications such as email spa...
