The GANNFL Approach uses a steady state Genetic Algorithm (GA) to build and train hybrid classifiers which are combinations of Neural Networks (NN's) and Fuzzy Logic (FL). This novel approach finds both the architecture, the types of the hidden units, the types of the output units, and all weights ! The designed modular and tight GA encoding together with the GA fitness function lets the GA develop high performance hybrid classifiers, which consist of NN parts and FL parts co-operating tightly within the same architecture. By analysing the behaviour of the GA it will be investigated whether there is evidence for preferring NN classifiers or FL classifiers. Further, the importance of the types of the hidden units is investigated. Parameter reduction is a very important issue according to the theory of the VC-dimension and Ockham's Razor. Hence, the GANNFL Approach also focuses on parameter reduction, which is achieved by automatically priming unnecessary weights and units. The GANNFL Approach was tested on 5 well known classification problems: The artificial, noisy monks3 problem and 4 problems representing difficult real-world problems that contain missing, noisy, misclassified, and few data: The cancer, card, diabetes and glass problems. The results are compared to public available results found by other NN approaches, the sGANN approach (simple GA to train NN's), and the ssGAFL approach (steady state GA to train FL classifiers). In every case the GANNFL Approach found a better or comparable result than the best other approach !
