I think this is a substantiative question on its own so it would be better to make a new question about it where you show your work step-by-step. It would be easier for other people to find the question and we will have more space for answers! :) | |

Actually I have one more question: In Xgboost paper formula 6 for a tree with depth 1 and number of trees=1 shows Similarity for the node which approximates minimum loss and should be equal to logloss value of the model. However when I calculate them with hands these two values are different. Why? | |
