【摘要】 根据人工神经网络模型,运用MATLAB的神经网络工具箱建立BP神经网络预测模型,以地震变化率作为神经网络的输入,对台湾地区和四川地区地震数据时间序列进行分析对大地震的发生时间进行预测。实验证明该模型用于地震预报的有效性和可行性,具有良好的应用价值。更多还原

【Abstract】 According to artificial neural network model,we build a BP neural network model based on the neural network toolbox of MATLAB.The seismic rate variations are inputs of neural network,through analysis of time series of earthquake data in Taiwan and Sichuan region to predict the occurrence of the large earthquake.Finally,experiment show that this model is not only effective and feasible for earthquake prediction but also has a good value.更多还原
