Hi Experts
I'm having a query with the input data set used in getting
recommendations (Collaborative Filtering). This is the scenario, I need to
recommend some item to the users based on the warehoused data from shopping
portal.The data set is Boolean. When I get into the data set to be used for
getting recommendations i have noticed the situation where the same user
making purchases of the same item multiple times. Hence there would be same
user-item pairs occurring multiple times in the data set
User1,Item1
User2,Item2
user3,Item3
User1,Item1
User1,Item2
User1,Item1
User2,Item3
User1,Item1
Here in the sample data set 'User1,Item1' pair occurs multiple times. How
would this repetition affect the recommendations in any way? Do I have to
employ a file preprocessor to eliminate these repetition before providing
the data set to mahout for computing recommendations?
Please advise.
Thank you
Regards
Bejoy.K.S
