1 code implementation22 Oct 2020 Benjamin Ricaud, Nicolas Aspert, Volodymyr Miz

Studying real-world networks such as social networks or web networks is a challenge.

What is Trending on Wikipedia? Capturing Trends and Language Biases Across Wikipedia Editions

1 code implementation17 Feb 2020 Volodymyr Miz, Joëlle Hanna, Nicolas Aspert, Benjamin Ricaud, Pierre Vandergheynst

In this work, we propose an automatic evaluation and comparison of the browsing behavior of Wikipedia readers that can be applied to any language editions of Wikipedia.

A Graph-structured Dataset for Wikipedia Research

1 code implementation20 Mar 2019 Nicolas Aspert, Volodymyr Miz, Benjamin Ricaud, Pierre Vandergheynst

It makes the parsing and extraction of relevant information cumbersome.

A Time-Vertex Signal Processing Framework

no code implementations5 May 2017 Francesco Grassi, Andreas Loukas, Nathanaël Perraudin, Benjamin Ricaud

An emerging way to deal with high-dimensional non-euclidean data is to assume that the underlying structure can be captured by a graph.

Tracking Time-Vertex Propagation using Dynamic Graph Wavelets

no code implementations21 Jun 2016 Francesco Grassi, Nathanael Perraudin, Benjamin Ricaud

Graph Signal Processing generalizes classical signal processing to signal or data indexed by the vertices of a weighted graph.

Global and Local Uncertainty Principles for Signals on Graphs

no code implementations10 Mar 2016 Nathanael Perraudin, Benjamin Ricaud, David Shuman, Pierre Vandergheynst

Accordingly, we suggest a new way to incorporate a notion of locality, and develop local uncertainty principles that bound the concentration of the analysis coefficients of each atom of a localized graph spectral filter frame in terms of quantities that depend on the local structure of the graph around the center vertex of the given atom.
