严格按照BP网络计算公式来设计的一个matlab程序,对BP网络进行了优化设计

优化1：设计了yyy，即在o(k)计算公式时，当网络进入平坦区时(<0.0001)学习率加大， 出来后学习率又还原

优化2：v(i,j)=v(i,j)+deltv(i,j)+a*dv(i,j) -A Matlab procedures in strict accordance with the BP network computing formula to design, the optimization design was carried out on BP network



Optimization design of 1: YYY, that is O (k) in the formula, when the network into the flat area (<0.0001) learning rate increase, after learning rate and reduction



Optimization of 2:v (I, J) =v (I, J)+deltv (I, J)+a*dv (I, J)
