Description

BinarizerMapper is a transformer to binarize a continuous variable using a threshold. The features greater than the threshold will be binarized 1.0 and the features equal to or less than threshold will be binarized to 0.

• Add BinarizerMapper for the operation of the binarizer.
• Add BinarizerParams for the params of BinarizerMapper.
• Add BinarizerMapperTest for the test example.
