-----------------------------------------
Summary:
ProbabilisticClassificationModel.normalizeToProbabilitiesInPlace should return
probabilities when given all-0 vector
Key: SPARK-18062
URL: https://issues.apache.org/jira/browse/SPARK-18062
Project: Spark
Issue Type: Improvement
Components: ML
Reporter: Joseph K. Bradley
Priority: Trivial
{{ProbabilisticClassificationModel.normalizeToProbabilitiesInPlace}} returns a
vector of all-0 when given a rawPrediction vector of all-0. It should return a
valid probability vector with the uniform distribution.
Note: This will be a *behavior change* but it should be very minor and affect
few if any users. But we should note it in release notes.
