About TMVA multi-background

Dear All,

I’m new to TMVA, when I tried TMVAMultipleBackgroundExample.C, the output is distributions and each background.

My question is:
is the multi-background results (training background separately) be the same as in TMVAClassification (add background together to training)?

Thanks!

Best,
Jung

They are similar but not exactly alike.

Hi Kim,

Thanks for the reply.

Is it possible to train each background and also all the background?

I add one branch of trainning all background, but the code running failed.

I wish to plot the stacking plots for each background, with the results of trainning all the backgrounds.

May I ask, are there some way to do this?

Thanks!

Best,

Jung
