Explanations

Bibliographic source

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

Mathematical principle

Random local wavelength warping.

Implementation

C ABI n4m_aug_local_warp_* in libn4m (create / apply / destroy lifecycle), wrapped by n4m.sklearn.LocalWarpAugmenter. The same numerical kernel backs every language binding.

Usage

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