Temporal network compression via network hashing
Rémi Vaudaine, Pierre Borgnat, Paulo Goncalves +2
Pairwise temporal interactions between entities can be represented as temporal networks, which code the propagation of processes such as epidemic spreading or information cascades,…
Fast Multiscale Diffusion on Graphs
Sibylle Marcotte, Amélie Barbe, Rémi Gribonval +4
Diffusing a graph signal at multiple scales requires computing the action of the exponential of several multiples of the Laplacian matrix. We tighten a bound on the approximation e…
Solving NMF with smoothness and sparsity constraints using PALM
Raimon Fabregat, Nelly Pustelnik, Paulo Gonçalves +1
Non-negative matrix factorization is a problem of dimensionality reduction and source separation of data that has been widely used in many fields since it was studied in depth in 1…
Analytic signal in many dimensions
Mikhail Tsitsvero, Pierre Borgnat, Paulo Gonçalves
In this work we extend analytic signal theory to the multidimensional case when oscillations are observed in the orthogonal directions. First it is shown how to obtain separate…
Design of graph filters and filterbanks
Nicolas Tremblay, Paulo Gonçalves, Pierre Borgnat
Basic operations in graph signal processing consist in processing signals indexed on graphs either by filtering them, to extract specific part out of them, or by changing their dom…
Localization bounds for the graph translation
Benjamin Girault, Paulo Gonçalves, Shrikanth Narayanan +1
The graph translation operator has been defined with good spectral properties in mind, and in particular with the end goal of being an isometric operator. Unfortunately, the result…
