Hello All, When I studied the code on the trunk, I was wondering that on line 130 in the class org.apache.mahout.cf.taste.hadoop.item.RecommenderMapper, shall we use the condition
userVector.get(index) == 0.0 instead? My understanding is that only the item which is not rated by the user (i.e., userVector.get(index) == 0.0) will be considered to add into the queue. Please correct me if I am wrong, Thanks, Guohua
