      Description

      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.
