Nicolò Ruggeri, Federico Battiston, Caterina De Bacco

AI总结:

针对超图领域结构化合成数据生成方法匮乏的问题,提出一种灵活高效的超图生成框架,支持指定社区结构与调整局部统计量,可用于算法评估与真实类超图生成,推动了高阶系统统计建模的发展。

摘要:

近年来,超图已成为研究包含多体相互作用系统的有力工具,这类多体相互作用无法被简单简化为成对相互作用。虽然生成合成数据的结构化程度较高的方法已被证明是算法标准化评估和真实世界网络数据统计研究的基础,但这类方法在超图领域却极为匮乏。在此,我们提出一种灵活且高效的框架,用于生成包含大量节点和大型超边的超图,该框架支持指定通用社区结构并调整不同的局部统计量。我们展示了如何使用我们的模型采样具备所需特征(同配或异配社区、混合或硬社区分配等)的合成数据、分析社区检测算法,以及生成结构上与真实世界数据相似的超图。我们的工作克服了此前合成超图生成方面的局限性,是高阶系统统计建模领域的一项重大进展。

英文摘要:

In recent years hypergraphs have emerged as a powerful tool to study systems with multi-body interactions which cannot be trivially reduced to pairs. While highly structured methods to generate synthetic data have proved fundamental for the standardized evaluation of algorithms and the statistical study of real-world networked data, these are scarcely available in the context of hypergraphs. Here we propose a flexible and efficient framework for the generation of hypergraphs with many nodes and large hyperedges, which allows specifying general community structures and tune different local statistics. We illustrate how to use our model to sample synthetic data with desired features (assortative or disassortative communities, mixed or hard community assignments, etc.), analyze community detection algorithms, and generate hypergraphs structurally similar to real-world data. Overcoming previous limitations on the generation of synthetic hypergraphs, our work constitutes a substantial advancement in the statistical modeling of higher-order systems.
