Subject recommender on binary data
Date Tue, 28 Jul 2009 14:59:26 GMT
I also built a recommender using taste which operates on a binary data set (an user has bought
or not bought a product). However, the recommender always return the same predicted value
for all test items (in other words, all test items are considered preferred by the recommender).
Did I do something wrong?
