方法二:利用贝叶斯定理 (Bayes' theorem) P(Xi) :指的是 A,B,C 三个机器生产的产品占比 P(Y|X_i) :指的是 A,B,C 三个机器生产出的产品中瑕疵品的占比(概率) 根据条件概率有 P(Y \cap X_i)=P(Y|X_i)P(X_i) ,所以: 最后根据贝叶斯定理可以计算出: P(X_C|Y) 后验概率 从上述结果会...

So a great way to learn Bayes Theorem, and in particular the implementation called Naive Bayes, is to think about how you track down a werewolf. So A is the variable you are trying to predict: It is a categorical variable that can be either A1 == werewolf or A2 == villager. Your ...
This article gives a mathematically rigorous yet easily accessible introduction to Bayes’ theorem and the foundations of naive Bayes learning. Starting from the fundamental elements of probability theory, this article outlines all steps leading to one of the oldest workhorses of machine learning: the...
Naive Bayes Theorm And Application - Theorem Naive Bayes model: 1. Naive Bayes model 2. model: discrete attributes with finit number of values 2. Parameter density estimation 3. Naive Bayes classification algorithm 4. AutoClass clustering alogrithm ...
Now, why "Bayes"? The algorithm employs Bayes' theorem to calculate probabilities, thus earning the name Naive Bayes. The algorithm is based on Bayes' theorem, which is a probability theory that relates the probability of an event based on prior knowledge of conditions that might be related to...
