pp_vsn — Variable Sorting Normalization

Group: Signal transforms · Binding: n4m.sklearn.VariableSortingNormalization · C ABI: n4m_pp_vsn_*

Description

VSN-style data-derived weighted SNV.

Parameters

Name	Type	Default
eps	float	1e-12

Explanations

Bibliographic source

Standard spectroscopic operator — see the nirs4all preprocessing / augmentation handbook and the cited literature within the binding docstring.

Mathematical principle

VSN-style data-derived weighted SNV.

Implementation

C ABI n4m_pp_vsn_* in libn4m (create / apply / destroy lifecycle), wrapped by n4m.sklearn.VariableSortingNormalization. The same numerical kernel backs every language binding.

Usage

from n4m.sklearn import VariableSortingNormalization
op = VariableSortingNormalization()
X_transformed = op.fit_transform(X)
