TMVA::MethodPDEFoam Class Reference

The PDEFoam method is an extension of the PDERS method, which divides the multi-dimensional phase space in a finite number of hyper-rectangles (cells) of constant event density.

This "foam" of cells is filled with averaged probability-density information sampled from a training event sample.

For a given number of cells, the binning algorithm adjusts the size and position of the cells inside the multidimensional phase space based on a binary-split algorithm, minimizing the variance of the event density in the cell. The binned event density information of the final foam is stored in binary trees, allowing for a fast and memory-efficient classification of events.

The implementation of PDEFoam is based on the Monte-Carlo integration package TFoam included in the analysis package ROOT.

◆ GetMvaValue()

Double_t TMVA::MethodPDEFoam::GetMvaValue ( Double_t err = nullptr,
Double_t errUpper = nullptr

virtual

Return Mva-Value.

In case of fSigBgSeparated==false (one unified PDEFoam was trained) the function returns the content of the cell, which corresponds to the current TMVA::Event, i.e. D = N_sig/(N_bg+N_sig).

In case of fSigBgSeparated==true (two separate PDEFoams were trained) the function returns

D = Density_sig/(Density_sig+Density_bg)

where 'Density_sig' is the content of the cell in the signal PDEFoam (fFoam[0]) and 'Density_bg' is the content of the cell in the background PDEFoam (fFoam[1]).

In both cases the error on the discriminant is stored in 'err' and 'errUpper'. (Of course err and errUpper must be non-zero and point to valid address to make this work.)
