Fourier Analysis of Signals on Directed Acyclic Graphs (DAG) Using Graph Zero-Padding
Ljubisa Stankovic, Milos Dakovic, Ali Bagheri Bardi +2
Directed acyclic graphs (DAGs) are used for modeling causal relationships, dependencies, and flows in various systems. However, spectral analysis becomes impractical in this settin…

Graph Fourier Transform Enhancement through Envelope Extensions
Ali Bagheri Bardi, Taher Yazdanpanah, Milos Dakovic +1
Many real-world networks are characterized by directionality; however, the absence of an appropriate Fourier basis hinders the effective implementation of graph signal processing t…
