Decision Tree algorithm

gainUsing some of the concepts of information entropy, in a sample set, the more "chaotic" the classification of a sample, the more information entropy it has, the more impure the sample is, and the more "neat" a sample is, the less information entropy it has, the purer the sample. The classification of samples is [1,1,1,0] than [1,1,0,0] good, the former is more "neat", more pure. So, if a property is divided into more pure samples, then the more we tend to choose this property.D is a collecti

MongoDB deposits non-homogeneous objects into the same collection

In MongoDB, the concept of ' table ' in the corresponding relational database is ' set ', the data structure in the table is consistent, MongoDB is stored in JSON format, the collection data is flexible, and the same set of MongoDB collection can hold different structures. The following are examples of testing in project development. 1.
