This is so embarassing
So I've been trying to follow along with the videos, manuals, etc. to get a sense for the RapidMiner workflow. It makes sense to me when I read about it, though in practice I am unable to get any results.
For example (and this has literally been the case with everything I've tried--whether it be with a sample dataset, one generated via operator, imported from Excel or CSV, etc.) I try to create a Split Validation (Decision Tree, then Apply Model and Performance)--I get all the yellows. When I click Play, however, and am returned to the Results view, I can't seem to find any results.
It's driving me crazy because it has to be something really obvious--and so humbly I ask for your help.
(The log file says I haven't specified a results file--though even when I do it generates an empty file).
On a somewhat related note, is the Excel Import Wizard in the current version different than what's shown in the videos? The screens don't look the same.
Thanks for your input!
