| 摘 要： | 为克服基于ＢＰ网络的实用预测建模中,盲目地过多训练网络所造成的网络“过度拟事”问题,本论述采用“早终止”方式的基于ＢＰ网络的预测建模方法,并以一选矿建模实例来说明这种方法的应用及“早终止”方式的具体实施途径。

| Abstract: | To overcome the "overfitting" of a BP model applied to modeling the practical prediction induced by over-training the BP model, the paper discussed the method of " early stopping" during training a BP model for prediction. The method was used in modeling a concentrate example. |
