bayesian network python

This paper illustrates the Python implementation method of naive Bayesian algorithm. Share to everyone for your reference. The implementation methods are as follows: Advantages and disadvantages of naive Bayesian algorithm Advantages: It is still valid in the case of less data, can deal with many kinds of problems Disadvantage: Sensitive to the way the input d
