摘要:

基于Agent的模型(ABM)强调了模拟验证的重要性,如定性的人脸验证和定量的经验验证。特别是,我们专注于定量验证,通过调整模拟输入参数的反弹道导弹。这项研究介绍了一个自动校准框架,结合了建议的动态和异构校准方法。具体而言,动态校准通过自动捕获合适的仿真时间来调整仿真参数,从而使仿真结果与真实世界数据相拟合。同时,异构校正通过分簇地调整Agent相关参数,减小了仿真中个体与真实世界个体之间的分布差异。

英文摘要:

Agent-based models (ABMs) highlight the importance of simulation validation, such as qualitative face validation and quantitative empirical validation. In particular, we focused on quantitative validation by adjusting simulation input parameters of the ABM. This study introduces an automatic calibration framework that combines the suggested dynamic and heterogeneous calibration methods. Specifically, the dynamic calibration fits the simulation results to the real-world data by automatically capturing suitable simulation time to adjust the simulation parameters. Meanwhile, the heterogeneous calibration reduces the distributional discrepancy between individuals in the simulation and the real world by adjusting agent related parameters cluster-wisely.
