Subject [jira] Commented: (MAHOUT-305) Combine both cooccurrence-based CF M/R jobs

Sean Owen commented on MAHOUT-305:
----------------------------------

Yeah it's just a small generalization -- what I'm up to reduces to the same thing if all ratings
are 1. You can make it run faster if there are no ratings involved, I'm sure.

I'm going to send you a draft of chapter 6 of MiA which has a complete writeup on this.

> We have two different but essentially identical MapReduce jobs to make recommendations
based on item co-occurrence: org.apache.mahout.cf.taste.hadoop.{item,cooccurrence}. They ought
to be merged. Not sure exactly how to approach that but noting this in JIRA, per Ankur.
