Explanations

Bibliographic source

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

Mathematical principle

Segment-wise correlation optimized warping approximation.

Implementation

C ABI n4m_pp_cow_align_* in libn4m (create / apply / destroy lifecycle), wrapped by n4m.sklearn.CorrelationOptimizedWarping. The same numerical kernel backs every language binding.

Usage

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