Dilation mapping transformer.

Quickstart

python
from sktime.transformations.dilation_mapping import DilationMappingTransformer

estimator = DilationMappingTransformer(dilation=2)

Parameters(1)

dilationint, default=2
The dilation factor. Determines the spacing between original data points in the transformed series. Must be an integer greater than 0. A dilation of 1 means no change, while higher values increase the spacing.

Examples

>>> from sktime.transformations.dilation_mapping import \
... DilationMappingTransformer
>>> from sktime.datasets import load_airline
>>> y = load_airline ()
>>> y_transform = DilationMappingTransformer (dilation = 2). fit_transform (y)
