Input

example set input

This input port expects an ExampleSet. It is output of the Retrieve operator in the attached Example Process.

Output

example set output

The ExampleSet with anid一个ttribute is output of this port.

original

The ExampleSet that was given as input is passed without changing to the output through this port. This is usually used to reuse the same ExampleSet in further operators or to view the ExampleSet in the Results Workspace.

Parameters

创建名义id

This parameter indicates if nominalidsshould be created instead of integerids.By default this parameter is not checked, thus integerids一个re created by default. Nominalids一个re of the format id_1, id_2, id_3 and so on.

Offset
