I know some questions have been made for example between gentle and ada, but I was wondering about gentle and the others.
For instance, I saw two different works talking about AdaBoost.M1 and AdaBoost.M2 and another work only addressing Gentle, Real and the original Adaboost.
It seemed to me that the Gentle was the latest and best one among gentle, real and original ; and that M2 was superior over M1.
I am not sure whoever what is the difference between (.M1 and .M2) versus the Gentle, Real and Original.
There is a package in R called ada which builds on top of Real, Gentle and the Original Adaboost, but since it does not address neither .M1 nor .M2 I couldn't compare which is one is better.
