Variational models for signal processing with Graph Neural Networks
Amitoz Azad, Julien Rabin, Abderrahim Elmoataz
This paper is devoted to signal processing on point-clouds by means of neural networks. Nowadays, state-of-the-art in image processing and computer vision is mostly based on traini…

Continuum limit of -Laplacian evolution problems on graphs: graphons and sparse graphs
Imad El Bouchairi, Jalal Fadili, Abderrahim Elmoataz
In this paper we study continuum limits of the discretized -Laplacian evolution problem on sparse graphs with homogeneous Neumann boundary conditions. This extends the results o…

Nonlocal -Laplacian Variational problems on graphs
Yosra Hafiene, Jalal Fadili, Abderrahim Elmoataz
In this paper, we study a nonlocal variational problem which consists of minimizing in the sum of a quadratic data fidelity and a regularization term corresponding to the $L^…
