A review of two decades of correlations, hierarchies, networks and clustering in financial markets
We review the state of the art of clustering financial time series and the study of their
correlations alongside other interaction networks. The aim of the review is to gather in one …

Entropic dynamic time warping kernels for co-evolving financial time series analysis
Network representations are powerful tools to modeling the dynamic time-varying financial
complex systems consisting of multiple co-evolving financial time series, eg, stock prices. In …

A quantum-inspired similarity measure for the analysis of complete weighted graphs
We develop a novel method for measuring the similarity between complete weighted
graphs, which are probed by means of the discrete-time quantum walks. Directly probing …

Graph motif entropy for understanding time-evolving networks
The structure of networks can be efficiently represented using motifs, which are those
subgraphs that recur most frequently. One route to understanding the motif structure of a …
