Xiangrui Meng updated SPARK-1359: --------------------------------- Target Version/s: 1.4.0 > SGD implementation is not efficient > ----------------------------------- > > Key: SPARK-1359 > URL: https://issues.apache.org/jira/browse/SPARK-1359 > Project: Spark > Issue Type: Improvement > Components: MLlib > Affects Versions: 0.9.0, 1.0.0 > Reporter: Xiangrui Meng > > The SGD implementation samples a mini-batch to compute the stochastic > gradient. This is not efficient because examples are provided via an iterator > interface. We have to scan all of them to obtain a sample. -- 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
