Is it possible to train a classifier using two tuples (signal/background, MC/data) that have different variable names? For example, some variables are called
PIDx in background, and
PIDx_corr in the signal tree.
I guess I’m imagining something like TMVA::DataLoader::AddVariable with two
TString expression arguments. But any workaround (without renaming the variables in the (large) tuples) would do. Thanks!
