Nick Pentreath commented on SPARK-13944: ---------------------------------------- FYI, I created a sort of "follow up" at SPARK-16365, to discuss in more detail ideas for {{mllib-local}} which may include the "local model / pipelines" etc > Separate out local linear algebra as a standalone module without Spark > dependency > --------------------------------------------------------------------------------- > > Key: SPARK-13944 > URL: https://issues.apache.org/jira/browse/SPARK-13944 > Project: Spark > Issue Type: New Feature > Components: Build, ML > Affects Versions: 2.0.0 > Reporter: Xiangrui Meng > Assignee: DB Tsai > Priority: Blocker > Fix For: 2.0.0 > > > Separate out linear algebra as a standalone module without Spark dependency > to simplify production deployment. We can call the new module mllib-local, > which might contain local models in the future. > The major issue is to remove dependencies on user-defined types. > The package name will be changed from mllib to ml. For example, Vector will > be changed from `org.apache.spark.mllib.linalg.Vector` to > `org.apache.spark.ml.linalg.Vector`. The return vector type in the new ML > pipeline will be the one in ML package; however, the existing mllib code will > not be touched. As a result, this will potentially break the API. Also, when > the vector is loaded from mllib vector by Spark SQL, the vector will > automatically converted into the one in ml package. -- 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
