MA Liang-lian · Journal of Daqing Normal University · 2013
A new kind of time series combined prediction model(PCA-BPNN model) is proposed,which the principal component analysis is used to reconstruct the original input space,and the network structure is determined based on the contribution rate of all main components.Finally,the incidence rate of gall-stone from January 1999 to December 2005 of Tianshui,Gansu province is used to validate the method.
