arXiv:2606.00758v1 Announce Type: cross Abstract: In recent years, graph signal processing has emerged as a powerful framework at the intersection of signal processing and graph theory, providing tools for the analysis of signals defined on nodes while accounting for their relationships represented by edges. These tools have been successfully applied to various settings, including statistical hypothesis testing. In particular, non-parametric approaches based on surrogate generation have been proposed for signals on undirected graphs. However, they are yet to be extended to directed graphs. In
The field of graph signal processing is rapidly advancing, leading to the imminent extension of robust statistical methods from undirected to more complex directed graphs.
This development enables more accurate and nuanced analysis of interconnected data in complex systems, crucial for various AI and data science applications.
Statistical hypothesis testing on directed graphs will become more sophisticated, mirroring the methods previously available only for undirected graphs.
