> tree Losses strings should match loss names
> -------------------------------------------
>
> Key: SPARK-5399
> URL: https://issues.apache.org/jira/browse/SPARK-5399
> Project: Spark
> Issue Type: Improvement
> Components: MLlib
> Affects Versions: 1.2.0, 1.2.1
> Reporter: Joseph K. Bradley
> Priority: Minor
>
> tree.loss.Losses.fromString expects certain String names for losses. These
> do not match the names of the loss classes but should. I believe these
> strings were the original names of the losses, and we forgot to correct the
> strings when we renamed the losses.
> Currently:
> {code}
> case "leastSquaresError" => SquaredError
> case "leastAbsoluteError" => AbsoluteError
> case "logLoss" => LogLoss
> {code}
> Proposed:
> {code}
> case "SquaredError" => SquaredError
> case "AbsoluteError" => AbsoluteError
> case "LogLoss" => LogLoss
> {code}
