Set Role
(Blending)
Synopsis
This Operator is used to change the role of one or more Attributes.Description
The role of an Attribute describes how other Operators handle this Attribute. The default role is regular, other roles are classified as special. The different types of roles are explained below in the parameter section.
An ExampleSet can have many special Attributes and you can assign special Attributes multiple times. This comes in handy, for example, if you want to feed the Attributes into a learner that accepts multiple labels. However, please note that some operators expect the special roles to be unique and they might not know how to handle duplicate special roles.
Differentiation
Renaming Operators
There are several Operator for renaming Attributes (e.g., Rename , Rename by Replacing, ...). Those only change the name of the Attribute and not its role.
