RapidMiner Regression using Subprocesses

In this video, we revisit regression in RapidMiner, but start to organize our process into subprocesses for a clean flow in the process workspace. We add regression-specific data prep to convert categorical features to indicator features. We switch to the purpose-built Split Validation operator to organize our modeling and testing activities. Finally, we also discuss documenting our work by customizing operator names in the workflow and adding descriptive notes.
