| Abstract: | How to construct or optimize the structure of Neural Network, as a hotspot of research in ANN, will affect the performance of it directly. This article applies the early-restart algorithm to the optimization of Neural Network′s structure, studies the character of optimal restart time in the algorithm, and advances the revisable structure of L-M (levernberg-marquardt) BP Neural Network based on early-restart algorithm. The comparative experiment shows that the early-restart algorithm can optimize the structu... |
