Member Function Documentation

◆ Estimate()

Float_t TMVA::PDEFoamKernelGauss::Estimate ( PDEFoam foam,
std::vector< Float_t > &  txvec,
ECellValue  cv 
)
virtual

Gaussian kernel estimator.

It returns the cell value 'cv', corresponding to the event vector 'txvec' (in foam coordinates) weighted by the cell values of all other cells, where the weight is a gaussian function.

Parameters:

  • foam - the pdefoam to search in
  • txvec - event vector in foam coordinates [0,1]
  • cv - cell value to estimate

Implements TMVA::PDEFoamKernelBase.

◆ GetAverageNeighborsValue()

Float_t TMVA::PDEFoamKernelGauss::GetAverageNeighborsValue ( PDEFoam foam,
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 when a cell value is undefined and the cell value shall be estimated by the (well-defined) cell values of the neighbor cells.

Parameters:

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

◆ WeightGaus()

Float_t TMVA::PDEFoamKernelGauss::WeightGaus ( PDEFoam foam,
PDEFoamCell cell,
std::vector< Float_t > &  txvec 
)
protected

Returns the gauss weight between the 'cell' and a given coordinate 'txvec'.

Parameters:

  • cell - the cell
  • txvec - the transformed event variables (in [0,1]) (coordinates <0 are set to 0, >1 are set to 1)

Returns:

\[ e^(\frac{-(\frac{d}{\sigma})^2}{2}) \]

where:

  • d - is the euclidean distance between 'txvec' and the point of the 'cell' which is most close to 'txvec' (in order to avoid artefacts because of the form of the cells).
  • \( sigma = \frac{1}{VolFrac} \)
