摘要

提出利用遗传神经网络技术对地震预测建模,其基本思想是利用遗传算法具有全局搜索能力、不易陷入局部极小点的特点优化神经网络的权重和阈值,利用优化的神经网络挖掘地震前兆异常属性和震级之间的潜在的关系,从而实现地震预测.并选取了《中国震例》中的97个样本数据进行实验,震例验证的结果表明,遗传神经网络算法用于大地震综合预测效果较理想.
A model of earthquake prediction based on genetic-neural network is presented.The main(idea) is that the genetic algorithm can carry through whole-space search and it will not get into local extremum.So the genetic algorithm is able to optimize the proportion and the numeral of the BP algorithm which can search the area that includes whole-space minimum.Hence,genetic-neural network can explore the underlying relation between the abnormity of earthquake and the level of earthquake.The paper utilizes 97 samples which are selected from THE ERRTHQUAKE EXAMPLES OF CHINA to test the model.The results show that the genetic-neural network algorithm is more efficient in the comprehensive earthquake prediction.
