Learning notes of machine learning practice: Classification Method Based on Naive Bayes, Probability is the basis of many machine learning algorithms. A small part of probability knowledge is used in the decision tree generation process, that is, to count the number of times a feature obtains a specific value in a dataset, divide by the total number of instances in the dataset to obtain the probability tha

### Bayesian, Naive Bayes, and call the spark official mllib naviebayes example

probability of B. Bayesian FormulaBayesian formula provides a method to calculate the posterior probability P (B | A) from the prior probability P (A), P (B), and P (A | B ). Bayesian theorem is based on the following Bayesian formula: P (A | B) increases with the growth of P (A) and P (B | A), and decreases with the growth of P (B, that is, if B is more likely to be observed when it is independent of A, then B's support for a is smaller.
