public class Interaction extends Transformer
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)
.
