Title:Hybrid connectionist - symbolic system
Author:Trifonov, RoumenDate:2002Abstract:Hybrid connectionist-symbolic systems incorporate several neural and symbolic modules, which interact to solve a problem. In this paper we describe a hybrid system (HCSS) in which the symbolic part is realized by neural network too. In this way we can bring all the benefits of the connectionist approach to the classical production systems. ...Library:
