> examples.MovieLensALS computes RMSE for movielens dataset but after addition of RankingMetrics and enhancements to ALS, it is critical to look at not only the RMSE but also measures like prec@k and MAP.
> In this JIRA we added RMSE and MAP computation for examples.MovieLensALS and also added a flag that takes an input whether user/product recommendation is being validated.
