Observing and Tracking Bandlimited Graph Processes
Elvin Isufi, Paolo Banelli, Paolo Di Lorenzo +1
One of the most crucial challenges in graph signal processing is the sampling of bandlimited graph signals, i.e., signals that are sparse in a well-defined graph Fourier domain. So…
Filter Design for Autoregressive Moving Average Graph Filters
Jiani Liu, Elvin Isufi, Geert Leus
In the field of signal processing on graphs, graph filters play a crucial role in processing the spectrum of graph signals. This paper proposes two different strategies for designi…
Adaptive Graph Signal Processing: Algorithms and Optimal Sampling Strategies
Paolo Di Lorenzo, Paolo Banelli, Elvin Isufi +2
The goal of this paper is to propose novel strategies for adaptive learning of signals defined over graphs, which are observed over a (randomly time-varying) subset of vertices. We…
Filtering Random Graph Processes Over Random Time-Varying Graphs
Elvin Isufi, Andreas Loukas, Andrea Simonetto +1
Graph filters play a key role in processing the graph spectra of signals supported on the vertices of a graph. However, despite their widespread use, graph filters have been analyz…
