Learning Persistent Community Structures in Dynamic Networks via Topological Data Analysis
Dexu Kong, Anping Zhang, Yang Li
The 38th Annual AAAI Conference on Artificial Intelligence (AAAI), 2024.
[Paper]
[Code]
[Arxiv]
We proposed a novel deep graph clustering framework with temporal consistency regularization on inter-community structures, inspired by
the concept of minimal network topological changes within short intervals.

Optimising self-organised volunteer efforts in response to the COVID-19 pandemic
Anping Zhang*, Ke Zhang*, Wanda Li, Yue Wang, Yang Li, Lin Zhang
Humanities and Social Sciences Communications, 2022.
[Paper]
[Project Page]
[Tsinghua News (in Chinese)]
[Tsinghua SIGS News]
A quantitive study on how volunteers collaborate to achieve rapid mobilisation during the COVID-19 outbreak, using the concept of self-organisation. It proposes a data-driven framework to investigate when and how self-organisation emerged during the pandemic response and how it relates to effectiveness of volunteer organisations in general.
