  abstract =     "Machine learning algorithms like Genetic Programming
                 (GP) can evolve biased classifiers when data sets are
                 unbalanced. In this paper we compare the effectiveness
                 of two GP classification strategies. The first uses the
                 standard (zero) class-threshold, while the second uses
                 the best class-threshold determined dynamically on a
                 solution-by-solution basis during evolution. These two
                 strategies are evaluated using five different GP
                 fitness across across a range of binary class imbalance
                 problems, and the GP approaches are compared to other
                 popular learning algorithms, namely, Naive Bayes and
                 Support Vector Machines. Our results suggest that there
                 is no overall difference between the two strategies,
                 and that both strategies can evolve good solutions in
                 binary classification when used in combination with an
                 effective fitness function.",
