时空神经网络及其在机场噪声预测中的应用
Space-time Neural Network and Its Application in Airport Noise Prediction
摘要
Abstract
A new space-time neural network is proposed using the function expansion technique and the linear impulse response filtering theory in this paper. It consists of function expansion and linear delay pulse. Net input space is mapped into a high dimensional space by function expansion. Therefore, nonlinear mode in low dimensional space can be converted to linear mode in high dimensional space. Linear delay pulse is equivalent to the temporal linear impulse response filter, which is responsible for fitting linear model in space-time series. Space-time neural network fast learning algorithm is proposed by using Levenberg-Marquardt optimization method. Simulation results show that space-time neural network has the characteristics of fast convergence and high precision. Compared with Space-time Autoregressive Moving Average(STARMA) and multilayer perceptron neural network, the prediction accuracy of the space-time neural network is significantly improved.关键词
