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)

-BP network in strict accordance with the formula to design a matlab program, the BP network optimization optimized　1: Design of yyy, ie o (k) formula, when the network into the flat zone ( " 0.0001) learning rate increased, came out again to restore the　learning rate optimization of 2: v (i, j) = v (i, j)+ deltv (i, j)+ a* dv (i, j)
