chemotools.adaptation
=====================

.. currentmodule:: chemotools.adaptation

Adaptation methods for calibration transfer between instruments. These transformers correct for differences in spectral axes or instrument response, allowing models trained on one instrument to remain valid on another.

**Import from this module:**

.. code-block:: python

   from chemotools.adaptation import (
       DirectStandardization,
       PiecewiseDirectStandardization,
       XAxisInterpolator,
   )
