Universal approximation using dynamic recurrent neural networks: discrete-time version
Jin Hao Liang, Μ.Μ. Gupta, PETER N. NIKIFORUK · 2002
In this paper, the approximation capability of a class of discrete-time dynamic recurrent neural networks (DRNNs) is studied. Analytical results presented show that some of the states of such a DRNN described by a set of difference equations may be used to approximate uniformly a state space trajectory produced by either a discrete-time nonlinear system or a continuous function on a closed discrete-time interval.
