abstract = "In this study we deal with the mixing problem, which
concerns combining the prediction of independently
trained local models to form a global prediction. We
deal with it from the perspective of Learning
Classifier Systems where a set of classifiers provide
the local models. Firstly, we formalise the mixing
problem and provide both analytical and heuristic
approaches to solving it. The analytical approaches are
shown to not scale well with the number of local
models, but are nevertheless compared to heuristic
models in a set of function approximation tasks. These
experiments show that we can design heuristics that
exceed the performance of the current state-of-the-art
Learning Classifier System XCS, and are competitive
when compared to analytical solutions. Additionally, we
provide an upper bound on the prediction errors for the
heuristic mixing approaches.",
