The decision tree method is used to model the decision process. The decision is based on the actual values of attributes in the data. The decision tree structure forks until a specific record can be predicted. In classification or regression, we use data to train decision trees.

the hypothesis of attribute condition independence, is often difficult to establish in reality, so it produces a "semi-naïve Bayesian classifier". The basic idea is to take proper consideration of the interdependent information among some attributes, so that we do not need to do a complete joint probability calculation, and do not completely ignore the strong attribute dependency. "Independent dependency Estimation" is the most common strategy, assuming that each property depends on a maximum o

discriminative model provides a mod El only for the target variable (s) conditional on the observed variables. Thus a generative model can be used, for example, to simulate (i.e. generate ) values of all variable in the Model, whereas a discriminative model allows only sampling of the target variables conditional on the observed quantities. On the other hand, despite the fact that discriminative models does not need to model the distribution of the observed Vari Ables, they cannot generally ex
