Github user tillrohrmann commented on the issue:

    @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. If your project does not have this feature
enabled and wishes so, or if the feature is enabled but not working, please
contact infrastructure at infrastructure@apache.org or file a JIRA ticket
with INFRA.
