複雑な介入を分析し、予期せぬ結果を予測するための数理モデリングの重要性。
Tiivistelmä
政府や政策立案者は複雑な介入に関する洞察を得るために数理モデリングを使用する必要があります。エージェントベースモデルは人口個人の微視的表現に幅広い柔軟性を持ち、実際の人口サイズで実行される場合、計算的需要が指数関数的に増加します。これらの課題に対処するため、代替手法や機械学習技術が活用されています。

Governments and policy makers usually need to meet sophisticated decisions for realizing complex interventions, e.g. regarding public health [Lorenc and Oliver, 2014].
Constructing and implementing realistic demographic ABMs is sought in many applications of SHCS s.a. Epidemiology, socio/health-economics, social care, health inequalities among others.
Overall, maximal exploitation of model-based mathematical analysis tools are thought s.a.: Monte-carlo based extensive simulations, Calibration with available data aiming at improving the predictive power of the model.
These tools need to be executed with care due to the challenging nature of common ABMs exhibiting strongly nonlinear chaotic behavior of model states.
A classical approach to overcome the huge computational demand for realizing model-based analysis of ABMs is to establish equivalent surrogates that accurately replicate not only the model behavior with tremendous speed up but also their structural features and statistical properties.
