Dual Margin Fitness Function
The Dual Margin fitness function
is a multi-objective function that explores the idea of a dual margin,
using a system of penalties to favor classifiers with larger margins.
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.
