Manning TITLE: Neural Networks in Fault Identification in Large Communication Networks IN: 2nd IEEE Mediterranean Symposium on New Directions in Control and Automation, Maleme-Chania, Crete, Greece, pp. 25 - 31, June 19-22, 1994. ABSTRACT In this work, we present our efforts in developing techniques for detecting the onset and diagnosis of a fault. The diagnosis domain in that of large Cable Television Networks. We are using stable recurrent neural networks to model the dynamic behavior of some of the measured parameters both for normal operation and during a fault. Deviations from the model indicate the onset of a fault, while the properties of the behavior during a fault are indicative of the fault modality.
