Hi I'm facing an issue with the attached exercise in connecting the ' Ser Role' operator to ' User knn' operator. Please I'm seeking some help to do step# 4 in the attached file to get the process running.
in this case you can use the similarity operators from rapidminer to create you own recommendation models. Please find attached a sample, using the operator available in new versions of RM.
that operator doesn`t work after version 10 of Rapidminer,
please check this thread about this discussion.
https://community.rapidminer.com/discussion/59497/set-role-doesnt-have-set-additional-roles-option
my recommendation is to use an alternative approach.
Can you share your dataset?
Best,
Cesar
