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…
Two-Timescale Stochastic Dispatch of Smart Distribution Grids
Luis M. Lopez-Ramos, Vassilis Kekatos, Antonio G. Marques +1
Smart distribution grids should efficiently integrate stochastic renewable resources while effecting voltage regulation. The design of energy management schemes is challenging, one…
Network Topology Inference from Spectral Templates
Santiago Segarra, Antonio G. Marques, Gonzalo Mateos +1
We address the problem of identifying a graph structure from the observation of signals defined on its nodes. Fundamentally, the unknown graph encodes direct relationships between…
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…
Network Topology Identification from Spectral Templates
Santiago Segarra, Antonio G. Marques, Gonzalo Mateos +1
Network topology inference is a cornerstone problem in statistical analyses of complex systems. In this context, the fresh look advocated here permeates benefits from convex optimi…
Stationary Graph Processes and Spectral Estimation
Antonio G. Marques, Santiago Segarra, Geert Leus +1
Stationarity is a cornerstone property that facilitates the analysis and processing of random signals in the time domain. Although time-varying signals are abundant in nature, in m…
