Explanations

Bibliographic source

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

Mathematical principle

Apply SNV independently inside fixed wavelength intervals.

Implementation

C ABI n4m_pp_piecewise_snv_* in libn4m (create / apply / destroy lifecycle), wrapped by n4m.sklearn.PiecewiseSNV. The same numerical kernel backs every language binding.

Usage

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