pp_dtw_align — Dynamic Time Warping Alignment

Group: Signal transforms · Binding: n4m.sklearn.DynamicTimeWarpingAlignment · C ABI: n4m_pp_dtw_align_*

Description

Dynamic-time-warping alignment to a fixed-length reference.

Parameters

Name	Type	Default
reference	—	None

Explanations

Bibliographic source

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

Mathematical principle

Dynamic-time-warping alignment to a fixed-length reference.

Implementation

C ABI n4m_pp_dtw_align_* in libn4m (create / apply / destroy lifecycle), wrapped by n4m.sklearn.DynamicTimeWarpingAlignment. The same numerical kernel backs every language binding.

Usage

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