The coefficient of variation of the spike rate is calculated in the limit of a large number of inputs using the integrated-input technique, which is extended here to include the effect of reversal potentials. The output spike rate is found to increase monotonically over two orders of magnitude, thereby solving the dynamic range (or gain control) problem. The coefficient of variation is approximately 1.0 for low input rates and increases to around 1.6 at high input rates, well within the range observed in the response of cortical neurons.","PeriodicalId":157719,"journal":{"name":"IJCNN'99.

However, there are many factors, which may affect the generalization ability of MLP networks, such as the number of hidden units, the initial values of weights and the stopping rules. These factors, if improperly chosen, may result in poor generalization ability of MLP networks. It is important to identify, these factors and their interaction in order to control effectively the generalization ability of MLP network. In this paper, we have empirically identified the factors that affect the generalization ability of MLP network, and compared their relative effect on the generalization performance.","PeriodicalId":157719,"journal":{"name":"IJCNN'99.

We use the SOM/LVQ network as a distribution service, apportioning an equal quantity of work to a number of intelligent nodes. Advantages include improved accuracy, effective and balanced multi-processing for small cluster systems, and potentially large reductions in training and recall times. The example problem chosen uses neural networks to model force dynamics of a coal train. The SOCM configuration used consists of a SOM network where each node is a backpropagation (BP) network. We show that the collection of as few as two BP networks gives at least a 30% reduction in approximation error when compared to the original BP network. We discuss how the SOCM approach could be used in other areas of artificial intelligence, including evolutionary systems, parallel processing, error balancing, hybrid networks, and online training.","PeriodicalId":157719,"journal":{"name":"IJCNN'99.

This paper addresses mine detection using commonly used electromagnetic induction sensors. We propose and evaluate two neural network approaches to mine detection which provide a robust nonparametric technique, based on training the networks using data from a previously calibrated portion of the minefield, or from a similar minefield. In the first approach, we combine a novel statistic, the S-statistic (which is a real valued variable related to the relative energy difference measured around a point in the minefield) with the /spl delta/-technique in a random neural network (RNN) design. In the second approach, a RNN is trained using a 3/spl times/3 block measurement window, and then applied as a postprocessor for the /spl delta/-technique. This RNN has an unconventional feedforward structure which realizes a matched filter to discriminate between nonmine patterns and mines. Experimental results for both approaches show that the RNN reduces false alarms substantially over the /spl delta/-technique and the energy detector.","PeriodicalId":157719,"journal":{"name":"IJCNN'99.

Because of certain limitations of ANNs, some investigators argue that Bayesian belief network (BBN) may exhibit higher performance. In this study we compared the performance of an ANN and a BBN used in the same CAD scheme. The common databases and the same genetic algorithm (GA) were used to optimize both networks. The experimental results demonstrated that using GA optimization, the performance of the two networks converged to the same level in detecting masses from digitized mammograms. Therefore, in this study we concluded that improving the performance of CAD schemes might be more dependent on optimization of feature selection and diversity of training database than on any particular machine classification paradigm.","PeriodicalId":157719,"journal":{"name":"IJCNN'99.

An abstract specification of the design is converted to a set of appropriate input vectors using a mathematical method, called \"multidimensional scaling\". These vectors which have, in general, higher dimensionality are fed to the self-organizing map at random in order to map them onto a 2D plane of the regular chip. The mapping is done in such a way that the cells with higher connectivity are placed close to each other, hence minimizing total connection length in the design. Two processes, called reassignment and rearrangement, are employed to make the algorithm applicable to the standard cell designs. In addition to the small examples introduced in other papers, two standard cell benchmarks were tried and better results were observed for these large designs compared to other neural net-barred approaches.","PeriodicalId":157719,"journal":{"name":"IJCNN'99.
