Enhanced False Balance Fitness Function
The Enhanced False Balance fitness function
is a multi-objective function that
explores the idea of a balance between the
false positives and
false negatives. It
is further enhanced by the optimization power of
positive correlations and can also
be combined
with a cost matrix in order to impose specific constraints on the
solutions.
In addition, by choosing different
rounding thresholds,
different fitness functions can be created to explore different solution spaces.
The evolvable rounding thresholds include the ROC threshold, the logistic, class proportions, large margin, average, RMS, interdecile mean,
interquartile mean, midrange, midhinge, and trimean threshold. There are also
two kinds of fixed thresholds: the rounding threshold of the active model and
user defined thresholds.
