Otis Gospodnetic updated MAHOUT-95:
-----------------------------------
Attachment: MAHOUT-95-diff-against-nearestN.txt
MAHOUT-95.patch
> UserSimilarity-based NearestNNeighborhood
> -----------------------------------------
>
> Key: MAHOUT-95
> URL: https://issues.apache.org/jira/browse/MAHOUT-95
> Project: Mahout
> Issue Type: Improvement
> Components: Collaborative Filtering
> Reporter: Otis Gospodnetic
> Priority: Minor
> Attachments: MAHOUT-95-diff-against-nearestN.txt, MAHOUT-95.patch,
> UserSimilarityNearestNUserNeighborhood.java
>
>
> A variation of NearestNUserNeighborhood. This version adds the minSimilarity
> parameter, which is the primary factor for including/excluding other users
> from the target user's neighbourhood. Additionally, the 'n' parameter was
> renamed to maxHoodSize and is used to optionally limit the size of the
> neighbourhood.
> The patch is for a brand new class, but we may really want just a single
> class (either keep this one and axe NearestNUserNeighborhood or add this
> functionality to NearestNUserNeighborhood), if this sounds good.
> I'll update the unit test and provide a patch for that if others think this
> can go in.
> Thoughts?
