| 摘 要： | 在BP算法中，误差函数不能有效地表征样本学习的误差程度，从而降低了学习的效果，本文提出了一种对误差函数的改进方案用以降低实际输出和期望输出的误差程度，计算机模拟表明效果良好。

| Abstract: | In BP algorithm,the error funcrion, which can not express the error of the sample-learning effectively,reduces the effectiveness of the aigorithm. This paper presents a new function,which is in the form of the relative error,The computer simplation results show that the new error function can help to reduce the relative error of the sample-learning. |
