Commonly, time series prediction problems are approached either from a stochastic perspective or, more recently, from a neural network perspective. Each of these approaches has advantages and disadvantages: stochastic methods are usually fast, but of limited applicability since they commonly employ only linear models. The NN methods, on the other hand, are powerful enough, but selecting an appropriate architecture and parameters is a time-consuming trial-and-error procedure.Combining the stochastic and NN methods may prove fruitful. This article explores the possibility of rapidly designing an appropriate neural network for time series prediction based on information obtained from stochastic modeling. Such an analysis could provide some initial knowledge regarding the choice of an NN architecture and parameters, as well as regarding an appropriate data-sampling rate.The motivation for this approach is that it is much more cost-effective to select an NN architecture with the help of linear stochastic modeling than by trial and error. The objective of this study is not to obtain "the optimal" NN architecture for a given problem, but to rapidly provide an architecture with close-to-optimal performance.Experiments on both a complex real-life prediction problem (an entertainment video-traffic series) and an artificially generated nonlinear time series on the verge of chaotic behavior (Mackey-Glass series) indicate that stochastic analysis can indeed provide some useful initial knowledge on which to base neural-network design. Although not necessarily optimal, such rapidly designed NN models performed comparably to or better than more elaborately designed NNs obtained through expensive trial-and-error procedures.
