void TMVA::PDEFoam::Explore ( PDEFoamCell * cell )

protectedvirtual

Internal subprogram used by Create.

It explores newly defined cell with help of special short MC sampling. As a result, estimates of kTRUE and drive volume is defined/determined Average and dispersion of the weight distribution will is found along each edge and the best edge (minimum dispersion, best maximum weight) is memorized for future use. The optimal division point for eventual future cell division is determined/recorded. Recorded are also minimum and maximum weight etc. The volume estimate in all (inactive) parent cells is updated. Note that links to parents and initial volume = 1/2 parent has to be already defined prior to calling this routine.

If fNmin > 0 then the total number of (training) events found in the cell during the exploration is stored in the cell. This information is used withing PeekMax() to avoid splitting cells which contain less than fNmin events.

Internal subprogram used by Create.

It finds cell with maximal driver integral for the purpose of the division. This function is overridden by the PDEFoam Class to apply cuts on the number of events in the cell (fNmin) and the cell tree depth (GetMaxDepth() > 0) during cell buildup.

		Int_t	idim2,
		ECellValue	cell_value = `kValue`,

		UInt_t	nbin = `50`
	)

virtual

Project foam variable idim1 and variable idim2 to histogram.

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 in TMVA::PDEFoamDiscriminant.

void TMVA::PDEFoam::RootPlot2dim	(	const TString &	filename,
		TString	opt,
		Bool_t	createCanvas = `kTRUE`,
		Bool_t	colors = `kTRUE`
	)

Debugging tool which plots the cells of a 2-dimensional PDEFoam as rectangles in C++ format readable for ROOT.

Parameters:

filename - filename of ouput root macro
opt - cell_value, rms, rms_ov_mean If cell_value is set, the following values will be filled into the result histogram:
- number of events - in case of classification with 2 separate foams or multi-target regression
- discriminator - in case of classification with one unified foam
- target - in case of mono-target regression If none of {cell_value, rms, rms_ov_mean} is given, the cells will not be filled. If 'opt' contains the string 'cellnumber', the index of each cell is draw in addition.
createCanvas - whether to create a new canvas or not
colors - whether to fill cells with colors or shades of grey

Example:

The following commands load a mono-target regression foam from file 'foam.root' and create a ROOT macro 'output.C', which draws all PDEFoam cells with little boxes. The latter are filled with colors according to the target value stored in the cell. Also the cell number is drawn.

TFile file("foam.root"); TMVA::PDEFoam foam = (TMVA::PDEFoam) gDirectory->Get("MonoTargetRegressionFoam"); foam->RootPlot2dim("output.C","cell_value,cellnumber"); gROOT->Macro("output.C");
