Another great contribution would be small or mid-sized datasets and gold master output sets for some of the standard computations. This problem requires both gold masters and evaluation algorithms for numerical variations against the masters. This would be very educational about how Recommenders,

I think it's far from complete or done. I think it would be interesting to take any of the MapReduce-based jobs, set it up, run it, and benchmark/profile it to locate some bottlenecks, then propose optimizations. It is a good way to get familiar with the packages. You might also investigate

I'd be very interested in benchmark data for and/or performance increases of RecommenderJob (as well as ItemSimilarityJob and RowSimilarityJob which are used internally), if you feel like working on that. A good starting point to get familiar with the functionality might be Sean's talk from

Hi Sean, Thanks for the immediate reply and sorry for my late response. Our above mentioned project is in progress. BTW I realized that Mahout is quite interesting and very active project. I am just interested about contributing to Mahout. As understanding the complete code base is not an easy

Hi Kasun, If you want to get involved, you are free to discuss and propose your own changes and algorithms. You can review the list of open issues here: https://issues.apache.org/jira/browse/MAHOUT This contains some ideas about work that needs to be done. One interesting project would be to
