mistakenly thought that no change It seems that the different data sets, the degree of change in the previous tree is not the same size naturally, there is a possibility that the front 1 trees as the back 3 trees, there may be a tree when five trees, so I can not support my own guess, so I basically could come to the conclusion that for GBDT, the front of the tree is more important than the tree behind, Through this research, I also observed some other phenomena, my own data set, convergence sp
