tslearn.utils.from_pyts_dataset

tslearn.utils.from_pyts_dataset(X)

Transform a pyts-compatible dataset into a tslearn dataset.

Parameters:

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

pyts-formatted dataset

Returns:

array, shape=(n_ts, sz, d)

tslearn-formatted dataset

Examples

>>> pyts_arr = numpy.random.randn(10, 16)
>>> tslearn_arr = from_pyts_dataset(pyts_arr)
>>> tslearn_arr.shape
(10, 16, 1)
>>> pyts_arr = numpy.random.randn(10, 2, 16)
>>> tslearn_arr = from_pyts_dataset(pyts_arr)
>>> tslearn_arr.shape
(10, 16, 2)
>>> pyts_arr = numpy.random.randn(10)
>>> from_pyts_dataset(pyts_arr)
