Dear ROOT experts,
Is there a way to automatically treat missing values for the input variables/features in the TMVA algorithms? An example could be a third jet variable in events that pass N(jets) >= 2 requirement.
There’s a 2-year old topic on this forum that says TMVA only supports padding the missing variable values with unphysical values. But in that topic there’s still no proof if this is a viable idea. Have anything changed since then? Does TMVA support the new ways to handle this issue?
Thanks in advance,
