英文摘要:
We develop a topology data analysis-based method to detect early signs for critical transitions in financial data. From the time-series of multiple stock prices, we build time-dependent correlation networks, which exhibit topological structures. We compute the persistent homology associated to these structures in order to track the changes in topology when approaching a critical transition. As a case study, we investigate a portfolio of stocks during a period prior to the US financial crisis of 2007-2008, and show the presence of early signs of the critical transition.

中文摘要:
我们开发了一种基于拓扑
数据分析的方法来检测财务数据中关键转换的早期迹象。从多个股票价格的时间序列出发,我们构建了具有拓扑结构的时间相关网络。我们计算与这些结构相关的持久同源性,以便在接近临界过渡时跟踪拓扑的变化。作为一个案例研究,我们调查了2007-2008年美国金融危机之前的一段时间内的股票组合,并显示了关键转型的早期迹象。
