چکیده

Recurrent neural networks have been established as a general tool for tting sequential input=output data. On the other hand, Fourier analysis is a useful tool for time series analysis. In this paper, these two elds are linked together to form a new interpretation to recurrent networks for time series prediction. Fourier analysis of a time series is applied to construct a complex-valued recurrent neural network. The proposed network is called Fourier Recurrent Network (ForeNet). We showed the proper parameter initialization and the learning algorithm for the complex weights in ForeNet. Experimental results show that ForeNet speeds up the learning, and the generalization performance is superior to traditional recurrent network.

Initialization of Recurrent Networks Using Fourier Analysis

Time-Delayed recurrent neural network models preserve information through time and are more powerful than the static feedforward networks, especially in dynamic problems. At present, recurrent networks are mostly formulated as nonlinear autoregression models [4] when applied to time series prediction problem. In this paper, we use a novel approach to interpret the recurrent networks. We build t...
