  abstract =     "This paper describes a technique which can be used
                 with Genetic Programming (GP) to reduce implicit bias
                 in binary classification tasks. Arbitrarily chosen
                 class boundaries can introduce bias, but if individuals
                 can choose their own boundaries, tailored to their
                 function set, then their outputs are automatically
                 scaled into a suitable range. These boundaries evolve
                 over time as the individuals adapt to the data. Our
                 system calculates the Evolved Class Boundary(ECB) for
                 each individual in every generation, with the twin aims
                 of reducing training times and improving test fitness.
                 The method is tested on three benchmark binary
                 classification data sets from the medical domain.

                 The results obtained suggest that the strategy can
                 improve training, validation and test fitness, and can
                 also result in smaller individuals as well as reduced
                 training times. Our approach is compared with a
                 standard benchmark GP system, as well as with over
                 twenty other systems from the literature, many of which
                 use highly tuned, non-EC methods, and is shown to yield
                 superior results in many cases.",
