用“提前停止”方法提高BP网络推广能力 本例将用提前停止和训练函数TRAINGDX相结合来避免“过度拟合”产生的误差 (The " early stopping" method to enhance the promotion of BP network capacity will be used in this case in advance and training function to stop the combination of TRAINGDX to avoid " over-fitting" error)

this modified PSO algorithm can solve for constrained optimization problem

Description: The function is called upon as follows: a = bemd(im1) im1 -> Image a(:,:,1) => IMF 1 a(:,:,2) => IMF 2 a(:,:,3) => IMF 3 a(:,:,4) => Residu
