摘    要:BP神经网络是目前水文预报中应用较为广泛的方法,但存在收敛速度慢、易陷入局部最优的缺陷.由此提出了基于全局优化打洞函数法的水文预报方法,把打洞函数法和BP神经网络相结合,利用打洞函数使BP算法跳出当前局部极小点,得到一个函数值更小的极小点,循环运算直至找到全局极小点.实验表明该水文预报方法能够提高预报精度,显示了良好的...

关 键 词:非线性规划  水文预报  打洞函数  BP神经网络

Abstract:BP neural network is widely used in hydrological forecasting.Aiming at the handicaps in present methods such as slow convergence and easily getting into local optimization, this paper presents a novel hydrological forecasting method based on the tunneling function which is one of the effective deterministic methods.The tunneling function method can find a lower minimizer by leaving the minimizer previously found.By repeating these processes,a global minimizer can be obtained at last.Experiments show the pro...
Keywords:nonlinear programming  hydrological forecasting  tunneling function  BP neural network
