.. py:class:: SubsampleTransform(parent: timesead.data.transforms.transform_base.Transform, subsampling_factor: int, aggregation: str = 'first')

   Bases: :py:obj:`timesead.data.transforms.transform_base.Transform`


   Subsample sequences by a specified factor. `subsampling_factor` consecutive datapoints in a sequence will be
   aggregated into one point using the `aggregation` function.

   :param parent: Another :class:`~timesead.data.transforms.Transform` which is used as the data source for this
       :class:`~timesead.data.transforms.Transform`.
   :param subsampling_factor: This specifies the number of consecutive data points that will be aggregated.
   :param aggregation: The function that should be applied to aggregate a window of data points.
      Can be either 'mean', 'last' or 'first'.

   .. py:property:: seq_len


.. py:class:: CacheTransform(parent: timesead.data.transforms.transform_base.Transform)

   Bases: :py:obj:`timesead.data.transforms.transform_base.Transform`


   Caches the results from a previous :class:`~timesead.data.transforms.Transform` in memory so that expensive
   calculations do not have to be recomputed.

   :param parent: Another :class:`~timesead.data.transforms.Transform` which is used as the data source for this
       :class:`~timesead.data.transforms.Transform`.


   .. py:attribute:: cache


.. py:class:: LimitTransform(parent: timesead.data.transforms.transform_base.Transform, count: int)

   Bases: :py:obj:`timesead.data.transforms.transform_base.Transform`


   Limits the amount of data points returned.

   :param parent: Another :class:`~timesead.data.transforms.Transform` which is used as the data source for this
       :class:`~timesead.data.transforms.Transform`.
   :param count: The max number of sequences that should be returned by this
       :class:`~timesead.data.transforms.Transform`.
