【摘要】 提出了一种改进算法，对原来的误差函数做了很小的改动。改进算法既保持了原ＢＰ算法的优点。又可以有效地避免假饱和，使学习过程可以较快地完成，取得了满意的结果，本文推导了改进后的算法，并结合实例对算法的效果进行了讨论．更多还原

【Abstract】 This paper presents an improvement in the Back Propagation(BP)algorithm.The new algorithm retains the best part of the old algorithm yet avoids fault saturation although it changes a small part of the error function.With these changes the study process can be completed quickly and with good results.This paper derives the impoved algorithm and discusses it using practical examples.更多还原
