I agree with Sean. I was thinking of splitting the dataset in the userVector formation job and creating a separate MapReduce phase in the end for evaluating (i am talking for the current RecommenderJob in o.a.m.cf.taste.hadoop.item). I will dig into this sometime next week and should be able to put it together.
(Even though my code will require multiple revisions before it can be included in mahout, i will just email a rough patch to Sean and then you can fix it whenever you get time). -- View this message in context: http://lucene.472066.n3.nabble.com/Evaluator-for-RecommenderJob-hadoop-implementation-tp1515638p1517829.html Sent from the Mahout User List mailing list archive at Nabble.com.
