  abstract =     "This paper investigates improvements to the fitness
                 function in Genetic Programming to better solve binary
                 classification problems with unbalanced data. Data sets
                 are unbalanced when there is a majority of examples for
                 one particular class over the other class(es). We show
                 that using overall classification accuracy as the
                 fitness function evolves classifiers with a performance
                 bias toward the majority class at the expense of
                 minority class performance. We develop four new fitness
                 functions which consider the accuracy of majority and
                 minority class separately to address this learning
                 bias. Results using these fitness functions show that
                 good accuracy for both the minority and majority
                 classes can be achieved from evolved classifiers while
                 keeping overall performance high and balanced across
                 the two classes.",
