-------------------------------
Summary: GenericItemBasedRecommender.estimate(id) method
confusing (line 347-349)
Key: MAHOUT-1303
URL: https://issues.apache.org/jira/browse/MAHOUT-1303
Project: Mahout
Issue Type: Bug
Components: Collaborative Filtering
Affects Versions: 0.9
Reporter: chsz wu
Assignee: Sean Owen
Priority: Minor
--------
if (excludeItemIfNotSimilarToAll || !Double.isNaN(estimate)) { -- line 347
average.addDatum(estimate);
}
-----
line 347 seems logic confusing,
if excludeItemIfNotSimilarToAll == true, -> always add data into average,
doesn't matter what the data is , Nan ???
