All Implemented Interfaces:
Serializable, Iterable<Regressor.DimensionTuple>, Output<Regressor>
Enclosing class:
Regressor
public static final class Regressor.DimensionTuple extends Regressor
A Regressor which contains a single dimension, used internally when the model implementation doesn't natively support multi-dimensional regression outputs.
