The GUI of setrole is broken? The learning video shows how you can type in special roles.
Set Role doesn't allow typing customized roles from the GUI. Customized Roles are needed for say, the recommendation extensions. The recommendation extension will try to generate them for you, but this is not standard.

Set Role messes with outlier detection, but setting role later ruins predictions
Hi, I've run into an interesting issue. If I assign a label to my target before standardization and outlier detection, my outliers are wrong. In general however the model performs OK. I do however have a few very significant outliers in the dataset that I would like to detect and remove. These are only found when…

Get and set roles from a reference data set
I have a data set with various features that have been excluded by marking them with a role (they were not removed because they can be useful for reference even if they should be excluded from most operators). Now, I would like to apply the same roles to another data set that has the same columns (on which no roles have…

I want to apply a threshold to the "Predicted" attribute to convert it into binomial values, then test its accuracy against the "Data" attribute. to use the operator "Apply Threshold", I had to make two real…

how to connect between Set Role operator and Apply Model operator
hi I have two questions. I would appreciate if you would guide me 1-I have a dataset with 5000 samples that do not have labels. On the other hand, I have another dataset with 100 samples labeled and the samples are not in the 5000 dataset. Is it okay to remove the label of 100 samples and cluster with clustering algorithms…

"Set Role doesn't work in tutorial"
In the final tutorial you've got to use the Set Role operator. I follow the instructions, but it just doesn't seem to work. It's as if the Attribute and Target Role aren't being recognised. When I run the process the error is "The attribute '' doesn't exist". Here is a screenshot:…

"Set Role and losing data"
So I have a data set which has an attribute (let's call it foo) as an id. And the values for each example are Strings - "a", "b", and so forth. I then pass that data through a Set Role "foo" to regular, and I lose most of the values of foo, but ONLY foo. So if a point went in ["foo":"c", "bar":"d", "cat":"dog"] it's coming…

"Data Importation: Set Role Issue"
Hi all! I am trying to use the dataset files from the UCI archive in ARFF format in RapidMiner, but I am facing a huge problem: most of the times, the set role operator does not pick the dataset from the ReadARFF operator and so I am not able to define the label attribute. This is weird because now and then, all of sudden,…
