Abstract:To explore a model for forecasting acquired immunodeficiency syndrome (AIDS) in Henan Province, and accurately and quickly predicting the future trend of AIDS, so as to provide reference for AIDS prevention and control. Methods Data of AIDS incidence in Henan Province from 2000 to 2014 were collected. The incidence prediction model was established using support vector machine. The data from 2000 to 2013 were taken as training samples, and the data of 2014 were used as testing sample. Average relative error was used to evaluate the effect of prediction. Then the model was utilized to predict the incidence of AIDS in Henan Province from 2015 to 2019. Results The average relative error of the established support vector machine model was 0.5512%. It is predicted that the incidences of AIDS in Henan Province from 2015 to 2019 are 0.85/105, 1.84/105, 1.64/105, 1.30/105 and 2.01/105 respectively. Conclusions Support vector machine model has high prediction accuracy and small error, and is suitable for AIDS prediction in Henan Province.
