Hey Guys, I'm new to rapidminer!
So I am trying to set an 'ignore' role to a number of my columns in rapidminer. So I search the "Set Role" from the repository then I initially input the column that I want to change the role to 'ignore' then I clicked on the "Edit List" to add the other column, after I've done this and run the process it only applies to one of the columns that I have modified. Is there anything that I can do to address this problem?
Solved! Go to Solution.
In RapidMiner, roles are unique. So in your scenario, you set one attribute after the other to that role, but in the end, only the last one retains the role.
What exactly do you want to do? Maybe you can make better use of the "Select Attributes" operator, which lets you select the attributes you want to use from then on.
