Application of Hybrid Genetic Algorithm in the Neural Network Model for Gray Iron Casting Fault Diagnosis
【摘要】 基于BP网络的强大缺陷诊断功能 ,构建了灰铸铁件缺陷诊断神经网络模型 ;针对BP算法学习网络权值收敛速度慢 ,易陷入局部最优的缺点 ,采用混合遗传算法加速网络权值的学习。
【Abstract】 A neural network model for gray iron casting fault diagnosis is constructed based on the mighty fault diagnosis function of BP neural network;To avoid the network get trapped in some local minimum and also to accelerate the weights learning,the hybrid genetic algorithms is used to learn BP neural network weights in this model;It is proved that the model can lower waster rate of gray iron casting effectively.
