Hybrid Neural Systems: From Simple Coupling to Fully Integrated Neural Networks

This paper describes techniques for integrating neural networks and symbolic components into powerful hybrid systems. Neural networks have unique processing characteristics that enable tasks to be performed that would be dicult or intractable for a symbolic rule-based system. However, a stand-alone neural network requires an interpretation either by a human or a rulebased system. This motivates the integration of neural/symbolic techniques within a hybrid system. A number of integration possibilities exist: some systems consist of neural network components performing symbolic tasks while other systems are composed of several neural networks and symbolic components, each component acting as a self-contained module communicating with the others. Other hybrid systems are able to transform subsymbolic representations into symbolic ones and vice-versa. This paper provides an overview and evaluation of the state of the art of several hybrid neural systems for rule-based processing.
