RRSE 2 Fitness Function
The RRSE 2 fitness function
is based on the
Root Relative Squared Error (RRSE).
The RRSE 2 component is implemented so that you can choose different
simple models besides the usual target average.
Moreover, the RRSE 2 differs from the common RRSE in the evaluation of the denominator term,
where instead of using the target output to calculate the difference between
the target and the simple model, the model output is used instead, resulting in a more dynamic,
forever adapting solution space.
The RRSE 2 fitness function can be combined
with a cost matrix in order to impose specific constraints on the
solutions.
In addition, the evolvable
logistic threshold, which is intrinsic to the
logistic regression model, can be adjusted by changing the number of bins.
