Xiangrui Meng updated SPARK-7770: --------------------------------- Assignee: Yanbo Liang > Should GBT validationTol be relative tolerance? > ----------------------------------------------- > > Key: SPARK-7770 > URL: https://issues.apache.org/jira/browse/SPARK-7770 > Project: Spark > Issue Type: Improvement > Components: ML, MLlib > Reporter: Joseph K. Bradley > Assignee: Yanbo Liang > Priority: Minor > > In spark.mllib, GBT validationTol uses absolute tolerance. Relative > tolerance is arguably easier to set in a meaningful way. Questions: > * Should we change spark.mllib's validationTol meaning? > * Should we use relative tolerance in spark.ml's GBT (once we add validation > support)? > I would vote for changing both to relative tolerance, where the tolerance is > relative to the current loss on the training set. -- 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
