------------------------------
Assignee: Maciej Szymkiewicz
> 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: 1.6.0, 2.0.0
> Reporter: Maciej Szymkiewicz
> Assignee: Maciej Szymkiewicz
> Priority: Minor
> Fix For: 1.6.3, 2.0.1, 2.1.0

>
> 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.
