PaddingTransformer

Padding panel of unequal length time series to equal, fixed length.

Quickstart

from sktime.transformations.padder import PaddingTransformer

estimator = PaddingTransformer(pad_length=None, fill_value=0)

Parameters(1)

pad_lengthint, optional (default=None) length to pad the series too.

if None, will find the longest sequence and use instead.

Examples

>>> import pandas as pd
>>> from sktime.transformations.padder import PaddingTransformer
>>> 
>>> # Create a sample nested DataFrame with unequal length time series
>>> data = {
... 'feature1': [
... pd. Series ([1, 2, 3 ]), pd. Series ([4, 5 ]), pd. Series ([6, 7, 8, 9 ])
... ],
... 'feature2': [
... pd. Series ([10, 11 ]), pd. Series ([12, 13, 14 ]), pd. Series ([15 ])
... ]
... }
>>> X = pd. DataFrame (data)
>>> 
>>> # Initialize the PaddingTransformer
>>> padder = PaddingTransformer ()
>>> 
>>> # Fit the transformer to the data
>>> padder. fit (X) PaddingTransformer()
>>> 
>>> # Transform the data
>>> Xt = padder. transform (X)
>>> 
>>> # Display the transformed data
>>> # print(Xt)
