State-Space Based Network Topology Identification
Mario Coutino, Elvin Isufi, Takanori Maehara +1
In this work, we explore the state-space formulation of network processes to recover the underlying structure of the network (local connections). To do so, we employ subspace techn…
Graph-Time Spectral Analysis for Atrial Fibrillation
Miao Sun, Elvin Isufi, Natasja M. S. de Groot +1
Atrial fibrillation is a clinical arrhythmia with multifactorial mechanisms still unresolved. Time-frequency analysis of epicardial electrograms has been investigated to study atri…
State-Space Network Topology Identification from Partial Observations
Mario Coutino, Elvin Isufi, Takanori Maehara +1
In this work, we explore the state-space formulation of a network process to recover, from partial observations, the underlying network topology that drives its dynamics. To do so,…
Controllability of Bandlimited Graph Processes Over Random Time Varying Graphs
Fernando Gama, Elvin Isufi, Alejandro Ribeiro +1
Controllability of complex networks arises in many technological problems involving social, financial, road, communication, and smart grid networks. In many practical situations, t…
Generalizing Graph Convolutional Neural Networks with Edge-Variant Recursions on Graphs
Elvin Isufi, Fernando Gama, Alejandro Ribeiro
This paper reviews graph convolutional neural networks (GCNNs) through the lens of edge-variant graph filters. The edge-variant graph filter is a finite order, linear, and local re…
On the Transferability of Spectral Graph Filters
Ron Levie, Elvin Isufi, Gitta Kutyniok
This paper focuses on spectral filters on graphs, namely filters defined as elementwise multiplication in the frequency domain of a graph. In many graph signal processing settings,…
