public class Interaction extends Transformer implements HasInputCols, HasOutputCol, DefaultParamsWritable
For example, given the input feature values Double(2) and Vector(3, 4), the output would be
Vector(6, 8) if all input features were numeric. If the first feature was instead nominal
with four categories, the output would then be Vector(0, 0, 0, 0, 3, 4, 0, 0).

public StructType transformSchema(StructType schema)
PipelineStageCheck transform validity and derive the output schema from the input schema.
We check validity for interactions between parameters during transformSchema and
raise an exception if any parameter value is invalid. Parameter value checks which
do not depend on other parameters are handled by Param.validate().
Typical implementation should first conduct verification on schema change and parameter validity, including complex parameter interaction checks.
