我们提出了一个使用模拟优化方法的近实时流感流行预测框架。该方法结合基于个体的模型和简单的寻根优化方法进行参数估计和预测。在这项研究中,利用谷歌流感趋势对2004-2005年、2007-2008年和2012-2013年流感季节流感活动的网络估计,对季节性流感流行进行了回顾性预测。在某些情况下,可以提前5-6周预测峰值。这项研究增加了流感预测的现有资源,所提出的方法可以在一个综合框架中与其他方法结合使用。
We present a framework for near real-time forecast of influenza epidemics using a simulation optimization approach. The method combines an individual-based model and a simple root finding optimization method for parameter estimation and forecasting. In this study, retrospective forecasts were generated for seasonal influenza epidemics using web-based estimates of influenza activity from Google Flu Trends for 2004-2005, 2007-2008 and 2012-2013 flu seasons. In some cases, the peak could be forecasted 5-6 weeks ahead. This study adds to existing resources for influenza forecasting and the proposed method can be used in conjunction with other approaches in an ensemble framework.
