Subject [jira] [Created] (SPARK-15119) DecisionTreeParams.minInfoGain does not have a validator
Date Wed, 04 May 2016 09:22:12 GMT
Dominik Jastrzębski created SPARK-15119:
-------------------------------------------

             Summary: DecisionTreeParams.minInfoGain does not have a validator
                 Key: SPARK-15119
                 URL: https://issues.apache.org/jira/browse/SPARK-15119
             Project: Spark
          Issue Type: Bug
          Components: ML
    Affects Versions: 1.6.1, 1.6.0
            Reporter: Dominik Jastrzębski
            Priority: Trivial


Information gain for splits in decision trees is always non-negative (see: https://en.wikipedia.org/wiki/Mutual_information#Definition_of_mutual_information),
so minInfoGain parameter in DecisionTreeParams could have a validator assuring that the value
is >= 0.
