SAXlegacy

Symbolic Aggregate approXimation (SAX) transformer.

Quickstart

from sktime.transformations.dictionary_based import SAXlegacy

estimator = SAXlegacy(word_length=8, alphabet_size=4, window_size=12, remove_repeat_words=False, save_words=False, return_pandas_data_series=True)

Parameters(11)

word_length: int, length of word to shorten window to (using

PAA) (default 8)

alphabet_size: int, number of values to discretise each value

to (default to 4)

window_size: int, size of window for sliding. Input series

length for whole series transform (default to 12)

remove_repeat_words: boolean, whether to use numerosity reduction (

default False)

save_words: boolean, whether to use numerosity reduction (

default False)

return_pandas_data_series: boolean, default = True

set to true to return Pandas Series as a result of transform. setting to true reduces speed significantly but is required for automatic test.
