[jira] [Created] (SPARK-17027) PolynomialExpansion.choose is prone to integer overflow

Maciej Szymkiewicz created SPARK-17027:
------------------------------------------

             Summary: PolynomialExpansion.choose is prone to integer overflow 
                 Key: SPARK-17027
                 URL: https://issues.apache.org/jira/browse/SPARK-17027
             Project: Spark
          Issue Type: Bug
          Components: ML
    Affects Versions: 2.0.0, 1.6.0
            Reporter: Maciej Szymkiewicz
            Priority: Minor


Current implementation computes power of k directly and because of that it is susceptible to integer overflow on relatively small input (4 features, degree equal 10).  It would be better to use recursive formula instead.
