This problem only causes a waste of neurons,but also results in the training error too great to meet the request of training precision and hardly completes the task of classification or clustering.
竞争型神经网络存在"死点"问题,某些神经元在竞争中可能始终未能获胜而成为"死神经元",不仅造成神经元的浪费,而且造成训练误差偏大,无法达到训练误差的精度要求,不能很好完成它所担负的聚类或分类任务。
2) analysis of mean square error function

4) Minimum classification error training
最小分类误差训练

Minimum classification error training method is used to incorporate the design of a linear transform matrixbased feature extractor and a classifier,which yields classification-oriented wavelet features and minimizes the error rate associate with the classifier.
在最小分类误差训练框架下,通过联合设计一个基于线性变换矩阵的特征提取器和一个分类器,来获取面向缺陷分类的小波框架特征,并最小化分类器的错误概率。
6) practice error
练习误差

亦称“恒定误差”。在同一条件下多次测量同一量时,误差的数值和符号保持不变,或在条件改变时,按某一确定的规律变化的误差。产生的主要原因:(1)分析方法不完善。如在重量分析中,由于沉淀的溶解和共沉淀现象等;在职滴定分析中,由于反应进行不完全和*等当点与滴定终点不符合等,均将系统地影响测定结果偏高或偏低。(2)仪器本身不够精确。如砝码重量、容量器皿刻度等。(3)试剂不纯。(4)操作者主观上带来的误差。如对滴定终点颜色的辨别不同等。为保证分析结果的准确度,对这类误差必须尽量减小以致消除。常采用标准试样和标准方法来进行校正,或由不同单位、不同人员测得的结果,进行对照和评价,从而得出校正系数以消除之。
