【摘要】 本文首先介绍了人工神经网络理论的基本内容以及前馈网络反向传播的训练方法，然后应用单隐含层网络作出船舶运动包络的实时预报。文中就一船舶的海上实测运动数据进行了实例计算，结果表明，本文方法的预报结果明显好于其它模型的自适应预报结果。更多还原

【Abstract】 The basic theory of neural network and the training method of back propagation for the feedforward net are described and the neuralnet with single hidden layer is used for real time prediction of the envelope of ship motions. As an example, the full scale duta of pitching motion of a ship are utilized for practical calculation. The results predicted by the neural network are obviously better than those by the other methods.更多还原
