-----------------------------------
Description:
We made several changes to ALS in 2.0. It is necessary to run some tests to
avoid performance regression. We should test (synthetic) datasets from 1
million ratings to 1 billion ratings.
cc [~mlnick] [~holdenk] Do you have time to run some large-scale performance
tests?
