Connecting the Dots: Identifying Network Structure via Graph Signal Processing
Gonzalo Mateos, Santiago Segarra, Antonio G. Marques +1
Network topology inference is a prominent problem in Network Science. Most graph signal processing (GSP) efforts to date assume that the underlying network is known, and then analy…
A Novel Scheme for Support Identification and Iterative Sampling of Bandlimited Graph Signals
Abolfazl Hashemi, Rasoul Shafipour, Haris Vikalo +1
We study the problem of sampling and reconstruction of bandlimited graph signals where the objective is to select a node subset of prescribed cardinality that ensures interpolation…
A Directed Graph Fourier Transform with Spread Frequency Components
Rasoul Shafipour, Ali Khodabakhsh, Gonzalo Mateos +1
We study the problem of constructing a graph Fourier transform (GFT) for directed graphs (digraphs), which decomposes graph signals into different modes of variation with respect t…
Blind Identification of Invertible Graph Filters with Multiple Sparse Inputs
Chang Ye, Rasoul Shafipour, Gonzalo Mateos
This paper deals with problem of blind identification of a graph filter and its sparse input signal, thus broadening the scope of classical blind deconvolution of temporal and spat…
