This repository is contains packages that helps building two kinds of tree models: Classification Tree and Regression Tree on the scalable enviroment with platform SPARK.

Paricularly, Regression Tree is implemented from CART algorithm of Breiman, which was introduced in 1984. Classification Tree has two types: Binary Classification Tree (implemented by CART ) and Multi-way Classification Tree (built by ID3).

Besides, you can do cross validation to prune tree models or use Random Forest to aggregate and increase the accuracy of prediction.
