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…

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…
