Dear Mahout team,
Need some advice. The books "Mahout/Hadoop in action" and online information

I am prototyping a solution for an analytics problem using User/Itemrecom
This is small enough that you can fit this into memory on one machine,
and you do not need Hadoop.
I would simply start with a GenericBooleanPrefItemBasedRecommender,
and attach it to a LogLikelihoodSimilarity similarity metric. Wrap the

I'm using Mahout 0.5.I am using Lucene ( the matching version in the

Thanks again.

Please have a look; comment or rewrite as you please. It's a wish list of
what I would want, approaching Mahout either as an experienced user or as a
