Uncertain Relation Suited to Overfitting of BP Neural Network
Uncertain Relation Suited to Overfitting of BP Neural Network
摘要
Abstract
A general uncertainty relation between the change of weighted value which represents learning ability and the discrimination error of unlearning sample sets which represents generalization ability is revealed in the modeling of back propagation (BP) neural network.Tests of numerical simulation for multitype of complicated functions are carried out to determine the value distribution (l×10-5~5×10-4) of overfitting parameter in the uncertainty relation.Based on the uncertainty relation,the overfitting in the training process of given sample sets using BP neural network can be judged.关键词
