Enhanced RSE 2 Fitness Function
The Enhanced RSE 2 fitness function
is a multi-objective function that combines the
Relative Squared Error (RSE)
with the
positive correl.
The RSE 2 component is implemented so that you can choose different
simple models besides the usual target average.
Moreover, the RSE 2 differs from the common RSE 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 Enhanced RSE 2 fitness can also 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.
