英文摘要	The ship swing motion has strong nonlinear and stochastic characteristics, so the ship swing motion prediction is very difficult. The paper designed a novel high precision RBF (radial basis function) neural network to predict the ship swing motion. In order to optimize the neural network structure, it used the embed dimension of time series to determine the number of input node and fuzzy clustering method to determine the initial number of hidden node for RBF neural network at first. Then it used the grey correlation analysis method to analyze the correlation degree between hidden node output and network output, and according to the size of correlation degree to delete the redundant hidden nodes. Meanwhile, in order to improve the prediction accuracy, it increased the direct connection between input layer and output layer in RBF neural network. Finally, the proposed model was tested with data from a real-world ship swing motion. Results show that the model maximum absolute error and mean squared error are respectively 0.2739 degree and 0.0110, so the proposed model is capable of prediction.
