------------------------------------

             Summary: Change the lambda weight to number of explicit ratings in implicit ALS
                 Key: SPARK-6642
                 URL: https://issues.apache.org/jira/browse/SPARK-6642
             Project: Spark
          Issue Type: Bug
          Components: MLlib
    Affects Versions: 1.3.0

Until SPARK-6637 is resolved, we should switch back to the 1.2 lambda weighting strategy to be consistent.
