[jira] Created: (MAHOUT-570) Make the retrieval of candidate items
for the most-similar-items computation customizable
Make the retrieval of candidate items for the most-similar-items computation customizable
-----------------------------------------------------------------------------------------
Key: MAHOUT-570
URL: https://issues.apache.org/jira/browse/MAHOUT-570
Project: Mahout
Issue Type: Improvement
Components: Collaborative Filtering
Affects Versions: 0.5
Reporter: Sebastian Schelter
When retrieving the initial set of possibly similar items in GenericItemBasedRecommender.doMostSimilarItems(...) only co-occurring items are selected. We need an exchangable strategy (similar to the existing CandidateItemsStrategy) in order to make this behavior customizable.
