This PDEFoam variant is used to estimate multiple targets by creating an event density foam (PDEFoamEvent), which has dimension:

dimension = number of variables + number targets

This PDEFoam variant stores in every cell the sum of event weights and the sum of the squared event weights. During evaluation for a given event, which has only variables and no targets (number of event variables is smaller than the foam dimension), the targets are estimated by finding all cells, which correspond to this event and calculate the Mean (or Mpv, depending on the ETargetSelection) cell center weighted by the event density in the cell.

This PDEFoam variant should be booked together with the PDEFoamEventDensity density estimator, which returns the event weight density at a given phase space point during the foam build-up.

◆ GetCellValue() [1/4]

Float_t TMVA::PDEFoam::GetCellValue	(	const PDEFoamCell *	cell,

	)

virtual

Returns the cell value of 'cell' corresponding to the given option 'cv'.

This function should be overridden by the subclass in order to specify which cell elements to return for a given cell value 'cv'. By default kValue returns cell element 0, and kValueError returns cell element 1.

This function is overridden from PDFEFoam.

It returns all regression targets (in order), given an untransformed event vector 'xvec'. The key of 'xvec' is the dimension and the value (Float_t) is the coordinate.

Note: number of foam dimensions = number of variables + number of targets

Parameters:

xvec - map of event variables (no targets!)
cv - cell value to return (ignored!)

Return: Targets, ordered by missing dimensions in 'xvec'. The size of the returned vector = foam dimension - size of xvec.

Parameters:

xvec - map for the untransformed vector. The key (Int_t) is the dimension, and the value (Float_t) is the event coordinate. Note that not all coordinates have to be specified.
cv - cell values to return

Return:

cell values from all cells that were found

xvec - event vector (untransformed, [fXmin,fXmax])
cv - the cell value to return
kernel - PDEFoam kernel estimator. If NULL is given, than the pure cell value is returned
