- ABSTRACT: In this thesis, a method is proposed with which good modular
- artificial neural network structures can be found automatically using a
- computer program. A number of biological metaphors are incorporated in
- the method. It will be argued that modular artificial neural networks
- have a better performance than their non-modular counterparts. The human
- brain can also be seen as a modular neural network, and the proposed
- search method is based on the natural process that resulted in the brain:
- Genetic algorithms are used to imitate evolution, and L-systems are used
- to model the kind of recipes nature uses in biological growth.
-
- A small number of experiments have been done to investigate the
- possibilities of the method. Preliminary results show that the method
- does find modular networks, and that those networks outperform 'standard'
- solutions. The method looks very promising, although the experiments
- done were too limited to draw any general conclusions. One drawback is
- the large amount of computing time needed to evaluate the quality of a
- population member, and therefore in chapter 9 a number of possible
- improvements are given on how to increase the speed of the method, as
- well as a number of suggestions on how to continue from here.

- Unfortunately, I'm not in the position to distribute paper-copies of this
- thesis. Questions and remarks are most welcome.
