Description
`Binarizer` takes a column of continuous features and output a column with binary features, where nonzeros (or values below a threshold) become 1 in the output.
val binarizer = new Binarizer() .setInputCol("numVisits") .setOutputCol("visited")
The output column should be marked as binary. We need to discuss whether we should process multiple columns or a vector column.
