Abstract Value Members

  1. abstract def evaluate(split: Split[V, T]): Option[(Split[V, T], Double)]

    Evaluate the fitness of a candidate split.

    Evaluate the fitness of a candidate split.

    This method may transform the split, in which case the score applies to the split that is returned. The result is optional to handle cases where a split is not valid (for example, if one side of a split is "empty" in some sense).
