pjml.stream.reduce.summ.Summ¶

class
pjml.stream.reduce.summ.
Summ
(field: str = 'R', function: str = 'mean', **kwargs)[source]¶ Given a field, summarizes a Collection object to a Data object.
The resulting Data object will have only the ‘s’ field. To keep other fields, consider using a Keep containing all the concurrent part: Keep(Expand -> … -> Summ).
The cells of the given field (matrix) will be averaged across all data objects, resulting in a new matrix with the same dimensions.

__init__
(field: str = 'R', function: str = 'mean', **kwargs)[source]¶ Initialize self. See help(type(self)) for accurate signature.

Lazily calculated unique identifier for this dataset. wrapped
Same as unwrap(), but with the external container Wrap. -
classmethod
default_config
() → Dict[str, Any][source]¶ Create a copy of the component default configuration.
Returns: - dict
Copy of the component default configuration.
-
id
[source]¶ Short uuID First 8 chars of uuid, usually for printing purposes. First collision expect after 12671943 combinations. :return:
-
unwrap
[source]¶ Subpipeline inside the first Wrap().
Hopefully there is only one Wrap in the pipeline. This method performs a depth-first search.
Examples
>>> pipe = Pipeline( >>> File(name='iris.arff'), >>> Wrap(Std(), SVMC()), >>> Metric(function='accuracy') >>> ) >>> pipe.unwrap # -> Chain(Std(), SVMC())
-
updated
(**kwargs)[source]¶ Clone this component, optionally replacing given params.
Returns: - A ready to use component.
-
uuid
¶ Lazily calculated unique identifier for this dataset.
Should be accessed direct as a class member: ‘uuid’.
Returns: - A unique identifier UUID object.
