In the previous post we addressed some issue of decision tree, including instability, lack of smoothness, sensitivity to data, and etc. One solution is Boosting Method. In simple words Boosting combines multiple weak learners to get a powerful predic…
After talking about Information theory, now let's come to one of its application - Decision Tree! Nowadays, in terms of prediction power, there are many ensemble methods based on tree that can beat Decision Tree generally. However I found it necessar…
This is the second post in Boosting algorithm. In the previous post, we go through the earliest Boosting algorithm - AdaBoost, which is actually an approximation of exponential loss via additive stage-forward modelling. What if we want to choose othe…
