Detailed Description

Class to contain payload of everything needed for MVA based charged particle identification.

• ECLChargedPIDPhasespaceBinning object specifying the boundaries in N dimensions that define the categories (regions) under consideration,
• Vector of ECLChargedPIDPhasespaceCategory objects which contain specific settings for each category.

Member Function Documentation

getBinningVariables()

std::vector< std::string > getBinningVariables ( ) const

inline

Returns string definitions of the variables used in defining the phasespace categories.

Definition at line 440 of file ECLChargedPIDMVAWeights.h.

{return m_binningVariables;}

getLinearisedCategoryIndex()

unsigned int getLinearisedCategoryIndex ( std::vector< float >  values ) const

inline

Returns the flattened 1D index of the N dimensional phasespace category grid.

Parameters

values

N dimensional input vector of floats to be mapped to a globalBinIndex.

Definition at line 429 of file ECLChargedPIDMVAWeights.h.

    {
      if (!m_categories) {
        B2FATAL("No N dimensional grid was found in the ECLChargedPIDMVA DB payload. This should not happen! Abort...");
      }
      return m_categories->getLinearisedBinIndex(values);
    }

getPhasespaceCategories()

const std::unordered_map< unsigned int, ECLChargedPIDPhasespaceCategory > * getPhasespaceCategories ( ) const

inline

Returns the map of phasespaceCategories.

Definition at line 409 of file ECLChargedPIDMVAWeights.h.

{return &m_phasespaceCategories;}

getPhasespaceCategory()

const ECLChargedPIDPhasespaceCategory * getPhasespaceCategory ( const unsigned int  idx ) const

inline

Returns the ith ECLChargedPIDPhasespaceCategory.

Parameters

idx	index of ECLChargedPIDPhasespaceCategory.

Definition at line 404 of file ECLChargedPIDMVAWeights.h.

{return &m_phasespaceCategories.at(idx);}

isPhasespaceCovered()

bool isPhasespaceCovered ( const int  linearBinIndex ) const

inline

Returns bool whether or not the given values are within the phasespace covered by the trainings in the weightfile.

Parameters

linearBinIndex

global bin index.

Definition at line 415 of file ECLChargedPIDMVAWeights.h.

    {
      // if the vector of values passed falls outside the defined phasespace.
      if (linearBinIndex < 0) return false;
      // if the vector is within the defined phasespace but we do not provide an ECLChargedPIDPhasespaceCategory object for this bin.
      if (m_phasespaceCategories.count(linearBinIndex) == 0) return false;
      return true;
    }

setBinningVariables()

void setBinningVariables ( std::vector< std::string > &  binningVariables )

inline

Set string definitions of the variables used in defining the phasespace categories.

Parameters

binningVariables

string definitions of the variables used in defining the phasespace categories.

Definition at line 446 of file ECLChargedPIDMVAWeights.h.

{m_binningVariables = binningVariables;}

setWeightCategories()

void setWeightCategories ( ECLChargedPIDPhasespaceBinning *  h )

inline

Set the N dimensional grid representing the categories for which weightfiles are defined.

A multiclass MVA is trained for each phases-space region defined by the bin boundaries.

Parameters

h	the N dimensional ECLChargedPIDPhasespaceBinning object.

Definition at line 387 of file ECLChargedPIDMVAWeights.h.

{m_categories = h;}

storeMVAWeights()

void storeMVAWeights ( std::unordered_map< unsigned int, ECLChargedPIDPhasespaceCategory > &  phasespaceCategories )

inline

Store the ECLChargedPIDPhasespaceCategory objects into the payload.

Parameters

phasespaceCategories

a map of ECLChargedPIDPhasespaceCategory objects. Each object contains all the data required to process tracks in that phasespace. The map does not need to cover all phasespace regions.

Definition at line 395 of file ECLChargedPIDMVAWeights.h.

    {
      m_phasespaceCategories = phasespaceCategories;
    }

Member Data Documentation

m_binningVariables

std::vector<std::string> m_binningVariables

private

Stores the list of variables used to define the phasespace binning.

Definition at line 462 of file ECLChargedPIDMVAWeights.h.

m_categories

ECLChargedPIDPhasespaceBinning* m_categories = nullptr

private

An N Dimensional binning whose bins define the boundaries of the categories for which the training is performed.

It is used to lookup the correct file in the payload, given a reconstructed value vector.

m_phasespaceCategories

std::unordered_map<unsigned int, ECLChargedPIDPhasespaceCategory> m_phasespaceCategories

private

Stores the ECLChargedPIDPhasespaceCategory object for all the N dimensional categories.
