Function Documentation

void cacheTree

(

)

CacheTree input variables to tree format usable by TMVA

TMVA can not work with friend trees with indices, resp. with array of the measurements, resp aliases and functions

• input "flat tree" for MVA learning to be created with variables of interest
• AliTreePlayer::MakeCacheTree to create flat input tree for TMVA

void loadMVAReaders

(

)

Load regression and register it for later usage.

void loadMVAReadersBootstrap

(

)

Load array of regression -used later in the array regression evaluation (mean, median, rms)

void makeMVABootstrapMI

(

Int_t

nRegression = 10

)

Emulation of the TMVA bootstrap - training repeated several time with different subset of data TODO - Implement real bootstrap ( random sampling with replacement + other methods) in the TMVA (to check with ROOT) TODO - DNN example - TO USE DNN (Deep neural network) BLASS or CBLASS library has to be enabled in ROOT. This is not the case for the default aliBuild recipes

QAtrendingFitExample

0.) Remove regression file

1.) Load Input data

2.) Cache tree - TMVA expect variables - not functions and aliases

3.) Register fitters

4.) Make bootstrap regression

5.) Load array of regression readers

load one of the bootstrap method

load bootstrap arrays

6.) Draw example plots

6.1 Correlation plot - mean regression of resolutionMIP vs observed resolutionMIP

tree->Draw("AliNDFunctionInterface::EvalMVAStat(0,1,interactionRate, bz0,qmaxQASum,qmaxQASumR):resolutionMIP:run","run==QA.EVS.run","colz"); 

6.2 Draw ration regression/fit as function of run

tree->Draw("AliNDFunctionInterface::EvalMVAStat(0,1,interactionRate, bz0,qmaxQASum,qmaxQASumR):resolutionMIP:run","run==QA.EVS.run","colz"); 

6.3 compare of the regression RMS for method array 0 and method array1

tree->Draw("AliNDFunctionInterface::EvalMVAStat(0,1,interactionRate, bz0,qmaxQASum,qmaxQASumR):resolutionMIP:run","run==QA.EVS.run","colz");

void RegisterFitters

(

)

Register example methods used for regression

• BDT and MLP example
• DNN - for the moment not used as need BLASS library - not in default AliRoot
  • Naive adaptation of the DNN configuration from the ROOT tutorials TMVARegression.C -
  • slow 100 times smaller than MLP
  • lead to floating point exception
