Fourier Analysis of Signals on Directed Acyclic Graphs Using Graph Zero-Padding: Enabling Spectral Analysis While Preserving System Output
This paper introduces a novel graph zero-padding technique to enable Fourier analysis on directed acyclic graphs (DAGs) while preserving the output of graph filters, addressing the limitation of traditional methods that alter the graph's structure and impact system behavior.
Adaptive Joint Estimation of Time-Varying Vertex and Edge Signals on Graphs
The authors propose a novel algorithm called Adaptive Joint Vertex-Edge Estimation (AJVEE) for jointly and adaptively estimating time-varying signals on both vertices and edges of a graph, addressing the limitations of existing methods that primarily focus on static signals or only one type of signal.
