Yanbo Liang updated SPARK-19155:
--------------------------------
Description:
ML {{GeneralizedLinearRegression}} only support lowercase input for {{family}}
and {{link}} currently. For example, the following code will throw exception:
{code}
val trainer = new GeneralizedLinearRegression().setFamily("Gamma")
{code}
However, R glm only accepts families: {{gaussian, binomial, poisson, Gamma}}.
We should make {{family}} and {{link}} case insensitive.
was:
ML {{GeneralizedLinearRegression}} should support both uppercase and lowercase.
For example, the following code will throw exception currently:
{code}
val trainer = new GeneralizedLinearRegression().setFamily("Gamma")
{code}
Actually, R glm only accepts families: {{gaussian, binomial, poisson, Gamma}}.
We should make {{family}} and {{link}} case insensitive.
> MLlib GeneralizedLinearRegression family and link should case insensitive
