BDT numbers for different pT thresholds

I have obtained these numbers for three different pT thresholds i.e 5 GeV, 6 GeV and 7 GeV.

(I) Overtraining Check Plots

(a) pT > 7 GeV                                                                                             (b) pT > 6 GeV

      

 

(c) pT > 5 GeV

II) Background rejection vs signal efficiency plots

 

(a) pT > 7 GeV                                                                                             (b) pT > 6 GeV

  

 

(c) pT > 5 GeV

(III) Efficiency plots

 

(a) pT > 7 GeV                                                                                             (b) pT > 6 GeV

  

(c) pT > 5 GeV
