Debasish Das created SPARK-4231: ----------------------------------- Summary: Add RankingMetrics to examples.MovieLensALS Key: SPARK-4231 URL: https://issues.apache.org/jira/browse/SPARK-4231 Project: Spark Issue Type: Improvement Components: Examples Affects Versions: 1.2.0 Reporter: Debasish Das Fix For: 1.2.0
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. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
