#define IMP_OBJECT_METHODS(Name)
Define the basic things needed by any Object.
Single variable function.
virtual DerivativePair evaluate_with_derivative(double feature) const
Calculate score and derivative with respect to the given feature.
virtual double evaluate(double feature) const
Calculate score with respect to the given feature.
For backwards compatibility.
