Identify Duplicate examples

fbergstrand

I have a couple of different files I merge together and I'm trying to identify the values that appear in more than one file. 

 

I.e. i want to use the operator Remove Duplicate but with the function "Keep duplicates and remove all values only existing once. 

 

what is the best/ easiast approach to this?

hello @fbergstrand - welcome to the forum.  I think I wrote a post last year answering this exact question - look here http://community.rapidminer.com/t5/RapidMiner-Studio-Forum/Identify-Duplicate-examples/m-p/33431  Don't forget that you can search things like "find duplicate examples" in the "Search the community..." bar at the top of all Community pages.
