Joseph K. Bradley created SPARK-5399:
----------------------------------------
Summary: 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}
