Hi Mahouters! In the last couple of months we are trying to improve CMU GraphLab's large scale machine learning (http://graphlab.org) compatibility with Mahout. As a first step, we changed our open source license to Apache. Now we are working on writing some of the GraphLab wrapper code in Java, thus allowing for better interaction between the projects. Our vision is to use Mahout for the inherently parallel tasks for large scale data it is very good at, while having GraphLab functionality of more complex interactions of data.
I am looking for any Mahout users who have large scale matrices that are factorized using Mahout SVD, who want to try out GraphLab SVD solver. I wrote some code to allow for easy transition between Mahout SequetialAccessSparseVector to GraphLab's binary format. If anyone wants to try it out, instructions are found on: http://bickson.blogspot.com/2011/08/graphlab-and-mahout-compatability.html Any feedback is welcome! - Danny Bickson
