Member Function Documentation

◆ FillFoamCells()

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

This function fills an event into the discriminant PDEFoam.

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

Reimplemented from TMVA::PDEFoam.

Definition at line 94 of file PDEFoamDiscriminant.cxx.

◆ Finalize()

void TMVA::PDEFoamDiscriminant::Finalize ( )
virtual

Calc discriminator and its error for every cell and save it to the cell.

Reimplemented from TMVA::PDEFoam.

Definition at line 113 of file PDEFoamDiscriminant.cxx.

◆ Project2()

TH2D * TMVA::PDEFoamDiscriminant::Project2 ( Int_t  idim1,
Int_t  idim2,
ECellValue  cell_value,
PDEFoamKernelBase kernel,
UInt_t  nbin 
)
virtual

Project foam variable idim1 and variable idim2 to histogram.

The projection algorithm is modified such that the z axis range of the returned histogram is [0, 1], as necessary for the interpretation as a discriminator. This is done by weighting the cell values (in case of cell_value = kValue) by the cell volume in all dimensions, excluding 'idim1' and 'idim2'.

Parameters:

  • idim1, idim2 - dimensions to project to
  • cell_value - the cell value to draw
  • kernel - a PDEFoam kernel (optional). If NULL is given, the kernel is ignored and the pure cell values are plotted.
  • nbin - number of bins in x and y direction of result histogram (optional, default is 50).

Returns: a 2-dimensional histogram

Reimplemented from TMVA::PDEFoam.
