Virtual base Class for all MVA method.

MethodBase hosts several specific evaluation methods.

The kind of MVA that provides optimal performance in an analysis strongly depends on the particular application. The evaluation factory provides a number of numerical benchmark results to directly assess the performance of the MVA training on the independent test sample. These are:

The signal efficiency at three representative background efficiencies (which is 1 − rejection).
The significance of an MVA estimator, defined by the difference between the MVA mean values for signal and background, divided by the quadratic sum of their root mean squares.
The separation of an MVA x, defined by the integral
\[ \frac{1}{2} \int \frac{(S(x) - B(x))^2}{(S(x) + B(x))} dx \]
where \( S(x) \) and \( B(x) \) are the signal and background distributions, respectively. The separation is zero for identical signal and background MVA shapes, and it is one for disjunctive shapes.
The average, \( \int x \mu (S(x)) dx \), of the signal \( \mu_{transform} \). The \( \mu_{transform} \) of an MVA denotes the transformation that yields a uniform background distribution. In this way, the signal distributions \( S(x) \) can be directly compared among the various MVAs. The stronger \( S(x) \) peaks towards one, the better is the discrimination of the MVA. The \( \mu_{transform} \) is documented here.

The MVA standard output also prints the linear correlation coefficients between signal and background, which can be useful to eliminate variables that exhibit too strong correlations.

◆ GetMulticlassConfusionMatrix()

TMatrixD TMVA::MethodBase::GetMulticlassConfusionMatrix	(	Double_t	effB,

virtual

Construct a confusion matrix for a multiclass classifier.

The confusion matrix compares, in turn, each class agaist all other classes in a pair-wise fashion. In rows with index \( k_r = 0 ... K \), \( k_r \) is considered signal for the sake of comparison and for each column \( k_c = 0 ... K \) the corresponding class is considered background.

Note that the diagonal elements will be returned as NaN since this will compare a class against itself.

See also: TMVA::ResultsMulticlass::GetConfusionMatrix

Parameters

[in]	effB	The background efficiency for which to evaluate.
[in]	type	The data set on which to evaluate (training, testing ...).

Returns: A matrix containing signal efficiencies for the given background efficiency. The diagonal elements are NaN since this measure is meaningless (comparing a class against itself).
