Abstract

Modularity is required to resolve the data interference problems that usually plague monolithic designs. The presence of data interference shows from the learning curve of the net. Re-learning does not always remove the problem; then a modular structure can be used. However, there is no guarantee that data interference can be removed in the simple decomposition. Ensemble networks and mixed experts can be used for specific decompositions. On the other hand, there is not a generalized constructive method to achieve an efficient modularity. In this paper an information-theoretical approach to the decomposition of modular neural classifiers is presented, that allows for arbitrary hierarchies.
