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 optimized BP network design optimization 1: Design of the yyy, that is, o (k) formula, when the network into the flat areas (< 0.0001) increase learning rate large, after the optimization of learning rate reduction 2: v (i, j) = v (i, j)+ deltv (i, j)+ a* dv (i, j)
