An Improvement in the BP Algorithm
-
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.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.
