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.
