With the guide of non-linear program theory, by using interpolative steps and inexact line search, an improved conjugate gradient method was found, by which the training rate of BP networks increases by tens or hundreds of times. Moreover, the improved method is effective to solve non-linear equations for which Newton's method does not converge owing to the problems of the quadratic derivative and inverse matrix.
通过大量的数值模拟试验发现,在非线性规划理论的指导下采用间插步骤和不精确的一维搜索技术改进的共轭梯度法,是基于梯度和共轭方向的连续搜索算法中最有效的算法,这种算法使BP网络的训练速度提高几十到几百倍,使BP网络的实际应用效果大为改善;而且这种算法对于用牛顿法由于求二阶导数和求逆矩阵等问题难于收敛的非线性方程组的求解也是很有效的。
