Sean Owen resolved MAHOUT-882.
------------------------------
Resolution: Fixed
> TopItems.getTopUsers ignores rescoring
> --------------------------------------
>
> Key: MAHOUT-882
> URL: https://issues.apache.org/jira/browse/MAHOUT-882
> Project: Mahout
> Issue Type: Bug
> Reporter: Grant Ingersoll
> Assignee: Grant Ingersoll
> Priority: Minor
> Fix For: 0.6
>
>
> I believe TopUsers.getTopUsers() is not properly handling the
> rescoredSimilarity:
> {code}
> TopItems.getTopUsers:
> double rescoredSimilarity = rescorer == null ? similarity :
> rescorer.rescore(userID, similarity);
> if (!Double.isNaN(rescoredSimilarity) && (!full || rescoredSimilarity >
> lowestTopValue)) {
> topUsers.add(new SimilarUser(userID, similarity));
> {code}
> It is checking rescoredSimilarity for everything, but then not passing it in
> like getTopItems does.
