"Collobarative filtering using rapid miner."
I was wondering if a user based collaborative filtering can be designed as a rapid miner flow in rapid miner UI. I attempeted to design but I could not succeed. This is for education purpose, I am doing my dissertation and I would like to design a simple collaborative filtering engine in RM to explore the various recommendation techniques. Any help would be highly appreciated.
The steps are
1. I have a sample data set, users have provided ratings for items
2. I want to calculate the similarity between users
3. Recommendations should be made to active user based on the preferences of people like minded to him
