Calculate BDT score with python based xgboost BDT

Hi All,
I am trying to use python-based xgboost for my BDT analysis.

How do I calculate the BDT score after I am able to use “model.predict_proba”? I am looking for a snippet or a mathematical definition of BDT score after this step.



This is more a question for xgboost than ROOT. For ROOT TMVA you can look at the TMVA Users guide, in particular the section about decision trees.
