Jon Sondag commented on SPARK-2160: ----------------------------------- https://github.com/apache/spark/pull/1316 (also resolves SPARK-2152) > error of Decision tree algorithm in Spark MLlib > -------------------------------------------------- > > Key: SPARK-2160 > URL: https://issues.apache.org/jira/browse/SPARK-2160 > Project: Spark > Issue Type: Bug > Components: MLlib > Affects Versions: 1.0.0 > Reporter: caoli > Labels: patch > Fix For: 1.1.0 > > Original Estimate: 4h > Remaining Estimate: 4h > > the error of comput rightNodeAgg about Decision tree algorithm in Spark > MLlib , in the function extractLeftRightNodeAggregates() ,when compute > rightNodeAgg used bindata index is error. in the DecisionTree.scala file > about Line980: > rightNodeAgg(featureIndex)(2 * (numBins - 2 - splitIndex)) = > binData(shift + (2 * (numBins - 2 - splitIndex))) + > rightNodeAgg(featureIndex)(2 * (numBins - 1 - splitIndex)) > > the binData(shift + (2 * (numBins - 2 - splitIndex))) index compute is > error, so the result of rightNodeAgg include repeated data about "bins" -- This message was sent by Atlassian JIRA (v6.2#6252)
