dqa.tasks.ml.RandomizeAndSubsample#

class dqa.tasks.ml.RandomizeAndSubsample(ratio: float = 1, size: int | None = None, **kwargs)#

Randomly subsamples data to a specified relative ratio or absolute size.

Chooses a random sub-array of the input along the axis 0. The corresponding indices are drawn with replacement.

Parameters:

ratio (float, default=1) – The resulting array has the size ratio * original_size along axis 0.
size (int, default=None) – If specified, this determines the absolute size of the output along axis 0. If None, then the value given for ratio is considered.

Methods

finish()

Can perform actions that are required to clean up after the task has finished, e.g. close network connections etc.
