A Study on Prediction Model of BP Algorithm in Macroeconomics

Abstract

Under the guidance of economic theory, the macroeconomic system is deeply studied. Clarify the characteristics of the macroeconomic system and discuss the macro-economic pointer system. According to the complexity and openness of macro-economic system, qualitative analysis and quantitative analysis are combined to analyze macro-economy by the method of comprehensive integration. To study the conventional methods of quantitative prediction; Using artificial neural network technology, under the connection of polynomial fitting and BP neural network, the prediction model system is created, and the prediction model is modeled by this way, which greatly improves the prediction accuracy of the system. It is found that the macro economy under BP algorithm shows an upward trend of development.
