class ValueIndexer extends Estimator[ValueIndexerModel] with ValueIndexerParams with BasicLogging

Fits a dictionary of values from the input column. Model then transforms a column to a categorical column of the given array of values. Similar to StringIndexer except it can be used on any value types.
