    Hi,

    this is not an extension maintained by RapidMiner so I'm afraid I don't know the answer to that question.
    Checking out the marketplace page for the extension leads to their website
    You may find more information or contact possibilities there.

    Regards,
    Marco

    Hello,

    Thank you a lot, I contacted the person who wrote the code for this algorithm in RapidMiner and everything was clear:

    "the Most Popular algorithm is one of the "simple" recommendation algorithms in the extension. This algorithm stores view counts (how many times has this item been viewed from the users in the train set) for each item in the train set. When doing recommendation for a given user, it returns a view count for each item this user has not seen before and returns top-k items based on this count. "
