Method and Description

TransformProcess.Builder

TransformProcess.Builder.firstDigitTransform(String inputColumn, String outputColumn, FirstDigitTransform.Mode mode) FirstDigitTransform converts a column to a categorical column, with values being the first digit of the number. For example, "3.1415" becomes "3" and "2.0" becomes "2". Negative numbers ignore the sign: "-7.123" becomes "7". Note that two FirstDigitTransform.Modes are supported, which determines how non-numerical entries should be handled: EXCEPTION_ON_INVALID: output has 10 category values ("0", ..., "9"), and any non-numerical values result in an exception INCLUDE_OTHER_CATEGORY: output has 11 category values ("0", ..., "9", "Other"), all non-numerical values are mapped to "Other" FirstDigitTransform is useful (combined with CategoricalToOneHotTransform and Reductions) to implement Benford's law.
