Set Role

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?

Re: Set Role

Hi!

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.

Re: Set Role

Thanks for the reply!

 

So I have like 15 columns and I only want to make use of the 10 columns for making my decision tree as the other 5 are irrelevant.

Re: Set Role

And I also made use of the "Select Attributes" operator that you suggested and it worked!

 

Thank you so much!

Cheers!
