chemotools.adaptation

Adaptation methods for calibration transfer between instruments, together with metadata-aware transformation and validation utilities.

Import from this module:

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

from chemotools.adaptation.functions import subtract_reference
from chemotools.adaptation.validation import check_metadata_function

Available Classes

Class	Description
DirectStandardization	Linear calibration transfer via least-squares mapping between instruments
PiecewiseDirectStandardization	Piecewise calibration transfer using local least-squares windows
SpectralSpaceTransform	SVD-based shared latent space domain adaptation
XAxisInterpolator	Resample spectra onto a shared x-axis grid via interpolation
MetadataFunctionTransformer	Apply a callable with auxiliary inputs supplied through metadata routing

Available Functions

Function	Description
check_metadata_function	Validate a metadata-aware callable on representative data
subtract_reference	Subtract a shared or per-sample reference from spectra
divide_by_reference	Divide spectra by a shared or per-sample reference
scale_by_factor	Scale spectra by a scalar or array factor
add_offset	Add a shared or per-sample offset to spectra
