A stochastic retarded differential model for continuous-time, random, delayed NNs is related to the CAM dynamic of Cohen, Grossberg and Hopfield.
The asymptotic dynamical behaviour of continuous-time neural networks has been closely studied since the early 1980s. Only recently however have stochastic models (Ito diffusions) of such networks been studied in any detail. Such models allow one to study the effect of random environmental noise (for example, heat) on the dynamics; we may also incorporate delays due to the finite accumulation time of synaptic charges (Hopfield's "short term average") and we attempt to understand the effect of these disturbances on the dynamics.
This talk will present a stochastic retarded differential equation model for continuous-time, random, delayed neural networks. We will present some new work on the Content Addressable Memory dynamic of Cohen, Grossberg and Hopfield and the dynamic of global convergence, which attempts to answer the question: will such dynamical behaviour survive random, delayed disturbances?
