Peng Meng created SPARK-21623:
---------------------------------
Summary: Comments of parentStats on
ml/tree/impl/DTStatsAggregator.scala is wrong
Key: SPARK-21623
URL: https://issues.apache.org/jira/browse/SPARK-21623
Project: Spark
Issue Type: Improvement
Components: ML
Affects Versions: 2.3.0
Reporter: Peng Meng
Priority: Minor
{code:java}
* Note: this is necessary because stats for the parent node are not available
* on the first iteration of tree learning.
*/
private val parentStats: Array[Double] = new Array[Double](statsSize)
{code}
This comment is not right. Actually, parentStats is not only used for the
first iteration. It is used with all the iteration for unordered featrues.
