期望误差 meaning in English

anticipation error

Realization of improved bp algorithm - single output three layers " artificial neural network generator base on improved bp algorithm has been developed by the author , and the generator has some functions that the number of neuron in first and second layer and theirs related training parameters such as learning rate . momentum factor a and the value of sum error e can all be self - defined by the users ; connection weights and threshold in each layer ' s neuron training data and teaching signals can also be input or modified in the friendly interface
生成器功能是:网络结构中的第一、二层神经元个数和训练参数中的学习速率粉，动量因子a和期望误差值:可由用户在一定范围内自定义;各层的权值、阀值、网络初始样本值及教师值可在友好的界面下输入、修改。
