On the effect of synaptic fluctuations during retrieval processes in neural network models

We studied stochastic neural network models in which, in addition to long t erm learning, fast fluctuations of the synaptic intensities occur so that t he neuron activity update takes place assuming a set of synaptic intensitie s taken at random from a given distribution. The influence of this distribu tion on the performance of the retrieval process and on the general behavio r of the network is discussed. (C) 1999 Elsevier Science B.V. All rights re served.
