Subject Re: Boolean preferences and evaluation
Date Tue, 22 Jan 2013 16:40:23 GMT
I got 0 when I used GenericUserBasedRecommender in code 2 but when
using GenericBooleanPrefUserBasedRecommender score was not 0 . I
repeat the test with different data and again I got some results.
Moreover , when I use
     DataModel model = new FileDataModel(new File("ua.base"));
in code 2, the MAE score was higher.

When you say RMSE can't be used with boolean data, I assume MAE also
can't be used?

Thanks !
