Rethinking Sketching as Sampling: A Graph Signal Processing Approach
Fernando Gama, Antonio G. Marques, Gonzalo Mateos +1
Sampling of signals belonging to a low-dimensional subspace has well-documented merits for dimensionality reduction, limited memory storage, and online processing of streaming netw…
Blind Identification of Graph Filters
Santiago Segarra, Gonzalo Mateos, Antonio G. Marques +1
Network processes are often represented as signals defined on the vertices of a graph. To untangle the latent structure of such signals, one can view them as outputs of linear grap…
Rank regularization and Bayesian inference for tensor completion and extrapolation
Juan Andres Bazerque, Gonzalo Mateos, Georgios B. Giannakis
A novel regularizer of the PARAFAC decomposition factors capturing the tensor's rank is proposed in this paper, as the key enabler for completion of three-way data arrays with miss…
Recovery of Low-Rank Plus Compressed Sparse Matrices with Application to Unveiling Traffic Anomalies
Morteza Mardani, Gonzalo Mateos, Georgios B. Giannakis
Given the superposition of a low-rank matrix plus the product of a known fat compression matrix times a sparse matrix, the goal of this paper is to establish deterministic conditio…
