Abstract

In this paper, we describe a fault-tolerant Neuro-Fuzzy inference system for performing fuzzy reasoning using coarse-coded distributed representations. The system implements the fuzzy membership functions in a novel way using coarse-coded distributed representations for the inputs and outputs of neural networks. Distributed representations are known to give advantages of fault tolerance, generalization and graceful degradation of performance under noise conditions. Performance of the Neuro-Fuzzy inference system with regard to its ability to exhibit fault tolerance under noise conditions is studied. The system offered very good results of fault tolerance under noise conditions. It has also exhibited good generalization ability on unseen test inputs.
