Regional economic development forecasting algorithm based on LPSVR

LIN Jian1,2,XIAO Jian-hua1,2(1.Systems Science and Technology Institute,Wuyi University,Jiangmen 529020,China;2.College of Economy and Management,Beijing University of Aeronautical and Astronautics,Beijing 100083,China)  
To solve the problems of high nonlinearity in indicator data of regional social systems and computation complexity of quadratic programming,a regional economic development forecasting algorithm based on LPSVR is proposed.The concept and detailed computation methods of forecasting trusting degree is introduced in LPSVR to solve the problem of reliability of forecast data.The introduction of a trade-off between empirical risk and confidence interval in the optimization of LPSVR leads to good generalization performance.LPSVR decreased computational complexity of time and space by replacing quadratic programming with linear programming.An experiment of forecasting economic development of Jiangmen was conducted,and the results and forecasting trusting degree are satis actory.
