中文简介:
在本次演讲中,我们将通过网络分析[1 4]显示有关金融系统中相关性的表征和可视化的结果。我们将讨论应用一种新方法的结果,该方法能够从互相关矩阵构造复杂的图形。检测到这些图的局部拓扑和层次结构的动态变化,并与市场波动相关[5]。 [1] T. Aste,T。Di Matteo,S。T. Hyde,Physica A 346(2005)20 26; [2] M.

课程简介: In this talk, we will show results concerning the characterization and visualization of correlations in financial systems by means of network analysis [1-4]. We will discuss results from the application of a new method which is able to construct complex graphs from cross-correlation matrices. Dynamical changes in the local topology and hierarchy of these graphs are detected and related to markets fluctuations [5]. [1] T. Aste, T. Di Matteo, S. T. Hyde, Physica A 346 (2005) 20-26; [2] M.
