A hybrid/symbolic connectionist production system

Abstract

The task of implementing a simple rule-based production system in terms of a hybrid symbolic/connectionist architecture is discussed. The aim is to achieve parallel execution of rules. The architecture uses a local representation and builds upon prior work, which resulted in the symbolic/connectionist expert system development tool SC-net. The Hybrid Symbolic/Connectionist Production System (HSC-PS) reported supports two types of working memory elements, the attribute/value pair and the object/attribute/value triplet. HSC-PS can provide variable binding in an individual condition and across conditions and variable value instantiation from the left-hand side to the right-hand side in a rule. The network is constructed from production rules such that only one value is bound to a variable at any one time. An implementation of the farmer's dilemma planning problem is given to illustrate the potential of this approach.<>
