Superset

Synopsis​

This operator takes two ExampleSets as input and adds new features of the first ExampleSet to the second ExampleSet and vice versa to generate two supersets. The resultant supersets have the same set of attributes but the examples may be different.

Description​

The Superset operator generates supersets of the given ExampleSets by adding new features of one ExampleSet to the other ExampleSet. The values of the new features are set to missing values in the supersets. This operator delivers two supersets as output:

  1. The first has all attributes and examples of the first ExampleSet + all attributes of the second ExampleSet (with missing values)
  2. The second has all attributes and examples of the second ExampleSet + all attributes of the first ExampleSet (with missing values)

include special attributes parameter can be used for changing this behavior. But it should be used carefully because even if this parameter is set to true, the resultant supersets can have only one special attribute of a kind. Please study the attached Example Process for better understanding.

Input​

example set 1​

This input port expects an ExampleSet. It is the output of the Retrieve operator in the attached Example Process. The output of other operators can also be used as input. It is essential that meta data should be attached with the data for the input because attributes are specified in their meta data.

example set 2​

This input port expects an ExampleSet. It is the output of the Retrieve operator in the attached Example Process. The output of other operators can also be used as input. It is essential that meta data should be attached with the data for the input because attributes are specified in their meta data.

Output​

superset 1​

The first superset of the input ExampleSets is delivered through this port.

superset 2​

The second superset of the input ExampleSets is delivered through this port.

Parameters​

Include special attributes​

This parameter indicates if the special attributes should be included for generation of the supersets. This operator should be used carefully especially if both ExampleSets have the same special attributes because the resultant supersets can have only one special attribute of a kind.
