For a very specific application of boosted decision trees, I would like to, after training my classifier with many trees, evaluate an event with a single one of those trees. I have found no method built into TMVA to do this (for good reason, I can’t imagine anyone wanting to do this outside of my project).
I see that in line 2353 of MethodBDT.cxx, the way this is done is through
This will work for me. My question then is how, given the xml weights file from my BDT, can I get the fForest vector so I can get a single tree object to do this to?
