      Description

      Q: Is there an EnsembleRecommender or CompoundRecommender that takes input
      from other recommender algorithms and combine them to generate better
      results?

      Ted Dunning:
      There isn't really any such thing although the SGD models are easy to glue
      together in this way.
      There is a guy named Praneet at UCI who is doing some feature sharding work
      that might relate to what you are doing. His email is
      praneetmhatre@gmail.com

      Sean Owen:
      There isn't. For the recommenders that work by computing an estimated
      preference value for items, I suppose you could average their
      estimates and rank by that.
      More crudely, you could stitch together the recommendations of
      recommender 1 and 2 by taking the top 10 amongst each of their top
      recommendations – averaging estimates where an item appears in both
      lists. That's much less work for you; it's not quite as "accurate".

      Danny Bickson:
      In terms of papers about ensemble methods/blending I suggest looking at the
      BigChaos Netflix paper:
      http://www.*netflixprize*.com/assets/*GrandPrize2009*_BPC_*BigChaos*.pdf
      See section 7.

        I'll work on this soon. Let's tentatively give it a 6-month dev period.

        Hi;

        I have some time to deal with this issue. If Mr. Zhou did not start to work on this I can contribute this issue.

        Sounds good. I haven't started coding yet. If you work on the code, I can do some code review too. Thanks.

        Perfect. Then I will start working on this in 2-3 days. I will be happy to have your code review. Thanks a lot.

        Mr. Dogan, are you still working on the EnsembleRecommender? I am asking because I will need to develop an EnsembleRecommender for a project that I will start working on this coming May.

        I'm going to consider this long since timed out. I don't see any effort to make a clean implementation.
