> Project: Mahout
> Issue Type: Bug
> Components: Collaborative Filtering
> Affects Versions: 0.5
> Reporter: Sean Owen
> Assignee: Sean Owen
> Fix For: 0.6

> An astute MiA reader points out that the FileDiffStorage class does not have
> a way to read diff counts, or the number of item-item pairs that resulted in
> the average diff. It is assumed to be 1, which causes it to be pruned
> quickly. The SlopeOneAverageDiffsJob needs to likewise output counts.
