estimator = DWTTransformer(num_levels=3)

Parameter(1)

num_levelsint, number of levels to perform the Haar wavelet
transformation.

Beispiele

>>> from sktime.transformations.dwt import DWTTransformer
>>> from sktime.datasets import load_airline
>>> from sktime.datatypes import convert
>>> 
>>> y = load_airline ()
>>> transformer = DWTTransformer (num_levels = 3)
>>> y_transformed = transformer. fit_transform (y)
