Xiangrui Meng updated SPARK-3022: --------------------------------- Target Version/s: 1.1.0 (was: 1.0.2) > FindBinsForLevel in decision tree should call findBin only once for each > feature > -------------------------------------------------------------------------------- > > Key: SPARK-3022 > URL: https://issues.apache.org/jira/browse/SPARK-3022 > Project: Spark > Issue Type: Improvement > Components: MLlib > Affects Versions: 1.0.2 > Reporter: Qiping Li > Assignee: Qiping Li > Fix For: 1.1.0 > > Original Estimate: 4h > Remaining Estimate: 4h > > `findbinsForLevel` is applied to every `LabeledPoint` to find bins for all > nodes at a given level. Given a specific `LabeledPoint` and a specific > feature, the bin to put this labeled point should always be same.But in > current implementation, `findBin` on a (labeledpoint, feature) pair is called > for every node at a given level, which is a waste of computation. I proposed > to call `findBin` only once and if a `LabeledPoint` is valid on a node, this > result can be reused. -- This message was sent by Atlassian JIRA (v6.2#6252) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
