Based on the Efficiency Coefficient-BP Neural Network Study of the Risk of Early Warning

Abstract

We all expect that we can predict the risk before it appears, the risk of early-warning has become a research hotspot in many fields, so does the economy of risk early-warning. In recent years, using Artificial Neural Network to solve the risk of early warning problem has been developed, but the risk of early warning process often encounters such a problem: The risk assessment has no standard, meanwhile BP Neural Network is a kind of instructors train, and instructors come from the standard. This paper combines Efficacy Coefficient Method and BP Neural Network to achieve the purpose of early warning on the economy problem, it has remedies the limitation of risk of early warning by simply using BP neural network.
Key words: Risk Early Warning, Efficiency Coefficient Method, BP Neural Network
