The authors show that two-layer nets with a single hidden layer are capable of forming disconnected decision regions. In addition to giving examples of the phenomenon, they explain why and how disconnected decision regions are formed. Assuming neural nodes with threshold elements, an expression is derived for the number of cells formed in the input space by(More)
In this paper we describe the English Conversational Telephone Speech (CTS) recognition system jointly developed by BBN and LIMSI under the DARPA EARS program for the 2004 evaluation conducted by NIST. The 2004 BBN/LIMSI system achieved a word error rate (WER) of 13.5% at 18.3xRT (real-time as measured on Pentium 4 Xeon 3.4 GHz Processor) on the EARS(More)
This article describes the benefits of microprocessor (muP) relay performance and its capabilities beyond previous protective relaying technologies. This article also discusses a multiple quality-measurement approach to observing, measuring, and then calculating muP relay reliability and unavailability.
Local rules theory describes virus capsid self-assembly in terms of simple local binding preferences of discrete subunit conformations. The theory offered a parsimonious explanation for the complexity and regularity of virus capsids that resolved several inconsistencies between experimental observations and prior theories. Simultaneously, it provided a(More)
We report on the results of the first evaluations for the BBN/LIMSI system under the new DARPA EARS Program. The evaluations were carried out for conversational telephone speech (CTS) and broadcast news (BN) for three languages: English, Mandarin, and Arabic. In addition to providing system descriptions and evaluation results, the paper highlights methods(More)
