Why graph signal processing?

Graph Signal Processing provides a new perspective for network data processing and its theoretical tools, such as Graph Fourier transform, graph sampling, reconstruction, graph filter, and graph wavelet.

What is graph in DSP?

A DSP program is often represented using a DFG, which is a directed graph (i.e., each edge has a distinct direction) that describes the program (see also Section 1.4. 3). For example, the program y(n) = ay(n − 1) + x(n) is graphically represented in Fig. 2.1(a). A simplified version of this program is shown in Fig.
