Content-Type: text/plain Message-Id: <20161110103023.3AF7EE00E5@git1-us-west.apache.org> Date: Thu, 10 Nov 2016 10:30:23 +0000 (UTC) archived-at: Thu, 10 Nov 2016 10:30:34 -0000 Github user tillrohrmann commented on the issue: https://github.com/apache/flink/pull/2542 @thvasilo you're right in the future we should make sure that we properly document how we came up with the testing data. What I've done to come up with the testing data for the `ALSITSuite` is to factorize the given recommendation matrix with Matlab with the given parameters (factors, iterations, etc). I've implemented ALS in Matlab for that. Ideally, we use a library for that so that others can reproduce the test results. I can share the ALS implementation if you like. Ideally we do something similar for iALS. --- If your project is set up for it, you can reply to this email and have your reply appear on GitHub as well.
