The Revisable Structure of Neural Network Based on Early Restart Algorithm and Its Application in Risk Evaluation of Venture Investment Items
Juan Peng · Systems Engineering-Theory Methodology Application · 2005
The structure of neural network, as a hotspot of research in ANN, will affect its performance and application directly. This article applies the early-restart algorithm to the optimizatioin of neural network's structure, studies the character of optimal restart time in the algorithm, and advances the revisable structure of classic BP neural network based on early-restart algorithm. We apply it in the risk evaluatioin of the venture capital investment tiems successfully. Comparing with classical BP neural network, we find that the early-restart algorithm can optimize the structure of neural network effectively, and has a significance meaning of being generalized.
