tslearn.utils.to_tsfresh_dataset

tslearn.utils.to_tsfresh_dataset(X)

Transform a tslearn-compatible dataset into a tsfresh dataset.

Parameters:

X: array, shape = (n_ts, sz, d)

tslearn-formatted dataset to be cast to tsfresh format

Returns:

Pandas data-frame

tsfresh-formatted dataset (“flat” data frame, as described there)

Notes

Conversion from/to tsfresh format requires pandas to be installed.

Examples

>>> tslearn_arr = numpy.random.randn(1, 16, 1)
>>> tsfresh_df = to_tsfresh_dataset(tslearn_arr)
>>> tsfresh_df.shape
(16, 3)
>>> tslearn_arr = numpy.random.randn(1, 16, 2)
>>> tsfresh_df = to_tsfresh_dataset(tslearn_arr)
>>> tsfresh_df.shape
(16, 4)
