摘要
介绍了通过控制综合误差改进的基于遗传算法的BP算法,以及该BP算法在土石坝渗流问题中的应用。实例计算表明,这种新方法与其它传统方法相比,网络训练速度明显加快,预测的精度也比较高,是土石坝渗流分析的一种有效可行的新思路和新方法。
Improved BP (Back Propagation Network) algorithm based on GA (Genetic Algorithm) by controlling synthetical error, and its application in analysis of seepage of dam are introduced in this paper. The example shows that the method has faster training speed and higher precision of prognostication than others. Therefore, it is concluded that the improved BP algorithm is a useful and effectual method in analysis of seepage of dam.
