Description

In SVM
http://madlib.apache.org/docs/latest/group__grp__svm.html#parameters
the `class_weight` parameter is not working properly.

I have not been able to get `class_weight=balanced` or `class_weight=

{a: 2, b: 3}

` or `class_weight=1` to work for me.

Actually I am not sure what the valid list of values for `class_weight`
is supposed to be.
