wildboar.utils.variable_len

Variable length utilities.

Functions

get_variable_length(x)	Return the length of each time-series.
is_end_of_series(x)	Test element-wise for EoS and return result as a boolean array.
is_variable_length(x)	Test if time-series is variable length.

wildboar.utils.variable_len.get_variable_length(x)

Return the length of each time-series.

Parameters:

xtime-series

The input.

Returns:

float or ndarray

The lenght of the time series.

Examples

>>> from wildboar.utils.variable_len import get_variable_length
>>> x = np.array(
...     [
...         [[1, 2, 3, eos], [1, 2, eos, eos], [1, 2, 3, 4]],
...         [[1, 2, 3, eos], [1, 2, eos, eos], [1, eos, 3, 4]],
...     ]
... )
>>> get_variable_length(x)
[[3 2 4]
 [3 2 4]]

>>> get_variable_length([1, 2, eos, eos])
2

>>> get_variable_length([[1, 2, eos, eos]])
[2]

wildboar.utils.variable_len.is_end_of_series(x)

Test element-wise for EoS and return result as a boolean array.

Parameters:

xndarray

Input array.

Returns:

ndarray

Boolean indicator array.

wildboar.utils.variable_len.is_variable_length(x)

Test if time-series is variable length.

Parameters:

xtime-series

The input.

Returns:

bool

True if time series contains EoS.
