| The list of variables on which the neural net is to train is set in the shell script, under TMVAvarset.txt (this file is created when the script runs). At present, these variables are: | ||||||||
| Changed: | ||||||||
| < < | The b-weights for the six 'leading' jets - currently the jets are ranked according to their b-weights, but it is possible to rank them according to pT and energy. The decision about how to rank them is done in the AOD -> NTuple stage: | |||||||

| NN_BJetWeight_Jet1 NN_BJetWeight_Jet2 NN_BJetWeight_Jet3 NN_BJetWeight_Jet4 NN_BJetWeight_Jet5 NN_BJetWeight_Jet6 | ||||||||
| Changed: | ||||||||
| < < | The masses and pT of the various jet combinations (only considering the four 'top' jets - i.e. if ranked by b-weights, the jets that we expect to really be b-jets in our signal: | |||||||
| > > | The masses and pT of the various jet combinations (only considering the four 'top' jets - i.e. if ranked by b-weights, the jets that we expect to really be b-jets in our signal: | |||||||

| < < | The sums of the eT of the two reconstructed tops, for each of the top three states: | |||||||

| NN_State1_SumTopEt NN_State2_SumTopEt NN_State3_SumTopEt | ||||||||
| Changed: | ||||||||
| < < | And the differences between the eta and phi of the two reconstructed tops, again from the top three states: | |||||||
| > > | And the differences between the eta and phi of the two reconstructed tops, again from the top three states: | |||||||
| NN_State1_DiffTopEta NN_State2_DiffTopEta NN_State3_DiffTopEta NN_State1_DiffTopPhi NN_State2_DiffTopPhi NN_State3_DiffTopPhi You also need to provide addresses to the Neural Net so that it can find the variables in the input trees. This is done inside VariableTreeToNTPATLASttHSemiLeptonic-v15.txt | ||||||||
