Explanations

Bibliographic source

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

Mathematical principle

Instrumental spectral broadening via Gaussian convolution.

Implementation

C ABI n4m_aug_instrument_broaden_* in libn4m (create / apply / destroy lifecycle), wrapped by n4m.sklearn.InstrumentalBroadeningAugmenter. The same numerical kernel backs every language binding.

Usage

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