------------------------------------------
Summary: Parallel item similarity precomputation on a single
machine
Key: MAHOUT-1167
URL: https://issues.apache.org/jira/browse/MAHOUT-1167
Project: Mahout
Issue Type: New Feature
Components: Collaborative Filtering
Affects Versions: 0.8
Reporter: Sebastian Schelter
Assignee: Sebastian Schelter
We need some code for item-based CF usecases with an intermediate data size
(e.g., a few million interactions). In such cases, the data might be too big to
allow online computation of similarities and recommendations, but at the same
time, going to Hadoop might still not be necessary and desired.
In such a case, it makes sense to precompute item similarities on a single
machine.
