- Parameters:
-
recommender | the IRecommender to use for making the predictions |
train | a user-wise IPosOnlyFeedback containing the items already observed |
candidate_items | list of candidate items |
num_predictions | number of items to return per user, -1 if there should be no limit |
filename | the name of the file to write to |
users | a list of users to make recommendations for |
user_mapping | an IMapping object for the user IDs |
item_mapping | an IMapping object for the item IDs |
repeated_items | true if items that a user has already accessed shall also be predicted |
