Twinning Complex Networked Systems: Data-Driven Calibration of the mABCD Synthetic Graph Generator

  • 从真实网络反推生成器参数,实现数字孪生
  • 多层参数间强耦合,独立估计不可行
  • 适合需要高保真仿真网络的研究者

关系数据的日益丰富推动了复杂系统网络化建模的发展。随着模型演化,多层网络逐渐被用来捕捉关系异质性等细微特征。然而,由于大规模实证数据稀缺,现有方法常依赖图生成器,但会引入系统性偏差。本文针对多层网络生成器 \\( mABCD \\\) 的逆向生成问题,提出从真实系统中反推其配置参数的方法,目标是生成能作为原结构数字孪生的合成网络。我们设计了参数匹配估计与误差量化机制。结果表明,该任务具有挑战性:参数间存在强相互依赖,独立估计失效,必须采用联合预测策略。

原文摘要 · Abstract (English)

The increasing availability of relational data has contributed to a growing reliance on network-based representations of complex systems. Over time, these models have evolved to capture more nuanced properties, such as the heterogeneity of relationships, leading to the concept of multilayer networks. However, the analysis and evaluation of methods for these structures is often hindered by the limited availability of large-scale empirical data. As a result, graph generators are commonly used as a workaround, albeit at the cost of introducing systematic biases. In this paper, we address the inverse-generator problem by inferring the configuration parameters of a multilayer network generator, \mABCD, from a real-world system. Our goal is to identify parameter settings that enable the generator to produce synthetic networks that act as digital twins of the original structure. We propose a method for estimating matching configurations and for quantifying the associated error. Our results demonstrate that this task is non-trivial, as strong interdependencies between configuration parameters weaken independent estimation and instead favour a joint-prediction approach.
