Bool_t TMVA::PDEFoamTarget::CellValueIsUndefined ( PDEFoamCell cell)
protectedvirtual

Returns true, if the target error equals -1, as set in Finalize() in case of no events in the cell.

Reimplemented from TMVA::PDEFoam.

Definition at line 134 of file PDEFoamTarget.cxx.

void TMVA::PDEFoamTarget::FillFoamCells ( const Event ev,
Float_t  wt 
)
virtual

This function fills an event into the discriminant PDEFoam.

The weight 'wt' is filled into cell element 0 if the event is of class 'fTarget', and filled into cell element 1 otherwise.

Reimplemented from TMVA::PDEFoam.

Definition at line 91 of file PDEFoamTarget.cxx.

void TMVA::PDEFoamTarget::Finalize ( )
virtual

Calculate average cell target in every cell and save them to the cell.

Cell element 0 will contain the average target and cell element 1 will contain the error on the target.

Reimplemented from TMVA::PDEFoam.

Definition at line 110 of file PDEFoamTarget.cxx.

Float_t TMVA::PDEFoamTarget::GetAverageNeighborsValue ( std::vector< Float_t > &  txvec,
ECellValue  cv 
)
protected

This function returns the average value 'cv' of only nearest neighbor cells.

It is used in cases, where empty cells shall not be evaluated.

Parameters:

  • txvec - event vector, transformed into foam coordinates [0, 1]
  • cv - cell value, see definition of ECellValue

Definition at line 173 of file PDEFoamTarget.cxx.

Float_t TMVA::PDEFoamTarget::GetCellValue ( const std::vector< Float_t > &  xvec,
ECellValue  cv,
PDEFoamKernelBase kernel 
)
virtual

This function finds the cell, which corresponds to the given untransformed event vector 'xvec' and return its value, which is given by the parameter 'cv'.

If cv == kValue, it is checked wether the cell value is undefined. If this is the case, then the mean of the neighbor's target values is returned, using GetAverageNeighborsValue().
