Obfuscate
(Productivity)
Synopsis
Replaces all nominal values and attribute names by random strings.Description
This operator takes an ExampleSet as input and maps all nominal values to randomly created strings. The names and the construction descriptions of all attributes will also replaced by random strings. This operator can be used to anonymize your data. It is possible to save the obfuscating map into a file which can be used to remap the old values and names. Please use the operator De-Obfuscator for this purpose. The new example set can be written with an ExampleSetWriter.
Input

Output
- example set (Data table)
- original (Data table)
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.
