Abstract
In many fields such as wind engineering, ocean engineering, soil engineering and so on, it is obvious that the development of effective methods to generate sample functions of non-Gaussian stochastic processes and fields is of paramount significance for many systems subjected to non-Gaussian excitations. In this paper, neural network technique is proposed for the conditional simulation of non-Gaussian stochastic processes and fields. In machine learning of neural network, interpolation is employed to train finite non-Gaussian samples. As numerical examples, the conditional simulation of non-Gaussian fluctuating wind pressures is carried out through using back propagation neural network and generalized regression neural network respectively.
