Hi Hani, I recently read about Souq.com. A vey promising project.
If you are looking at the spark-itemsimilarity for ecommerce type recommendations you may be interested in some slide decs and blog posts I’ve done on the subject. Check out: http://occamsmachete.com/ml/2014/10/07/creating-a-unified-recommender-with-mahout-and-a-search-engine/ http://occamsmachete.com/ml/2014/08/11/mahout-on-spark-whats-new-in-recommenders/ http://occamsmachete.com/ml/2014/09/09/mahout-on-spark-whats-new-in-recommenders-part-2/ Also I put up a demo site that uses some of these techniques: https://guide.finderbots.com Good luck, Pat On Dec 21, 2014, at 11:44 PM, AlShater, Hani <[email protected]> wrote: Hi All, I am trying to use spark-itemsimilarity on 160M user interactions dataset. The job launches and running successfully for small data 1M action. However, when trying for the larger dataset, some spark stages continuously fail with out of memory exception. I tried to change the spark.storage.memoryFraction from spark default configuration, but I face the same issue again. How could I configure spark when using spark-itemsimilarity, or how to overcome this out of memory issue. Can you please advice ?
