Scattering Spectra Models for Physics

no code implementations29 Jun 2023 Sihao Cheng, Rudy Morel, Erwan Allys, Brice Ménard, Stéphane Mallat

In this paper, we introduce scattering spectra models for stationary fields and we show that they provide accurate and robust statistical descriptions of a wide range of fields encountered in physics.

Unearthing InSights into Mars: Unsupervised Source Separation with Limited Data

1 code implementation27 Jan 2023 Ali Siahkoohi, Rudy Morel, Maarten V. de Hoop, Erwan Allys, Grégory Sainton, Taichi Kawamura

Source separation involves the ill-posed problem of retrieving a set of source signals that have been observed through a mixing operator.

Statistical description of dust polarized emission from the diffuse interstellar medium -- A RWST approach

1 code implementation16 Jul 2020 Bruno Regaldo-Saint Blancard, François Levrier, Erwan Allys, Elena Bellomi, François Boulanger

The RWST provides a statistical description of the polarization maps, quantifying their multiscale properties in terms of isotropic and anisotropic contributions.
