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…

Minibatch optimal transport distances; analysis and applications

Kilian Fatras, Younes Zine, Szymon Majewski +3

Optimal transport distances have become a classic tool to compare probability distributions and have found many applications in machine learning. Yet, despite recent algorithmic de…

Continuous dictionaries meet low-rank tensor approximations

Clement Elvira, Jeremy E. Cohen, Cedric Herzet +1

In this short paper we bridge two seemingly unrelated sparse approximation topics: continuous sparse coding and low-rank approximations. We show that for a specific choice of conti…

Sparsity-based audio declipping methods: selected overview, new algorithms, and large-scale evaluation

Clément Gaultier, Srđan Kitić, Rémi Gribonval +1

Recent advances in audio declipping have substantially improved the state of the art.% in certain saturation regimes. Yet, practitioners need guidelines to choose a method, and whi…

Training with Quantization Noise for Extreme Model Compression

Angela Fan, Pierre Stock, Benjamin Graham +4

We tackle the problem of producing compact models, maximizing their accuracy for a given model size. A standard solution is to train networks with Quantization Aware Training, wher…

Fast Optical System Identification by Numerical Interferometry

Sidharth Gupta, Rémi Gribonval, Laurent Daudet +1

We propose a numerical interferometry method for identification of optical multiply-scattering systems when only intensity can be measured. Our method simplifies the calibration of…
