I am trying to do some great Event recommandation using mahout.
For practice I tried following example-
https://github.com/RevBooyah/Static-mahout-recommender-tutorial/blob/master/ItemRecommend.java
I have some doubt that there are 3 things that used in data model UserId, ItemId and Preference as below-
But when I run the code with or without Preferences tha results are same, So my doubt is that what is the use of the Preferences ? If here it is useless then how can it be used for better Recommandation ?
I tried to find it but found nothing.
Can anyone please help me ?
