"Actually I need to show the decision logic also,other than improving the accuracy. That's the reason of not using Random forest.Do you think I can show the decision logic using Boosted additive model? Also I need to it for regression tree"

"Boosted additive models is the state of the art technique when it comes to classifications trees. The other benefit is that boosted additive models also address nonlinearity of the underlying data very well."

Improve accuracy of regression tree

Hi,I'm working on some analysis using regression tree. But the accuracy level of the tree is coming low. Can I suggest some methods which will improve the accuracy of regression tree & able to represent the splitting logic by building tree?I tried with Random forest. It is increasing the accuracy but I'm not able to represent my final outcome as a tree.Thanks in advanceSee More
