Implicit Bias of SGD for Diagonal Linear Networks: a Provable Benefit of Stochasticity

Nicolas Henri Bernard Flammarion, Scott William Pesme, Loucas Pillaud-Vivien

Understanding the implicit bias of training algorithms is of crucial importance in order to explain the success of overparametrised neural networks. In this paper, we study the dynamics of stochastic gradient descent over diagonal linear networks through i ...

Second harmonic generation from Chalcogenide metasurfaces via mode coupling engineering

Olivier Martin, Fabien Sorin, Jérémy Butet, Wei Yan, Dang Tùng Nguyen, Kuang-Yu Yang, Andreas Leber, Louis Marie Philippe Martin-Monier, Chaoqun Dong

Dielectric metasurfaces have shown prominent applications in nonlinear optics due to strong field enhancement and low dissipation losses at the nanoscale. Chalcogenide glasses are one of the promising materials for the observation of nonlinear effects due ...

Fractal-like Mechanical Resonators with a Soft-Clamped Fundamental Mode

Tobias Kippenberg, Alberto Beccari, Nils Johan Engelsen, Sergey Fedorov

Self-similar structures occur naturally and have been employed to engineer exotic physical properties. We show that acoustic modes of a fractal-like system of tensioned strings can display increased mechanical quality factors due to the enhancement of diss ...

On the Electronic and Optical Properties of Metal-Organic Frameworks: Case Study of MIL-125 and MIL-125-NH2

Berend Smit, Alfredo Pasquarello, Kyriakos Stylianou, Francesco Ambrosio, Gloria Capano, Stavroula Kampouri

The photo-active MIL-125 and MIL-125-NH2 metal-organic frameworks (MOFs), despite having a very similar crystalline structure, exhibit different optical behaviors. Luminescence in MIL-125 decays in about 1 ns, while for its amino counterpart, the lifetime ...

On data assimilation with Monte-Carlo-calculated and statistically uncertain sensitivity coefficients

Andreas Pautz, Mathieu Hursin, Daniel Jerôme Siefman

Sensitivity coefficients from Monte Carlo neutron transport codes have uncertainties that can affect nuclear data adjustments with integral experiments. This paper presents an extended version of Generalized Linear Least Squares (GLLS), called xGLLS, that ...

Adaptive phase correction of diffusion-weighted images

Jean-Philippe Thiran, Marco Pizzolato, Maxime Descoteaux

Phase correction (PC) is a preprocessing technique that exploits the phase of images acquired in Magnetic Resonance Imaging (MRI) to obtain real-valued images containing tissue contrast with additive Gaussian noise, as opposed to magnitude images which fol ...

When illusions merge

Michael Herzog, Aline Françoise Cretenoud

Recently, we found very weak correlations between the magnitudes of visual illusions. However, we found strong correlations between 19 variants of the Ebbinghaus illusion which differed in color, shape or texture, suggesting that different illusions make u ...

Linearity versus non-linearity in high frequency multilevel wind time series measured in urban areas

Dasaraden Mauree, Fabian Guignard, Mohamed Laib

In this paper, high frequency wind time series measured at different heights from the ground (from 5.5 to 25.5 meters) in an urban area were investigated. The spectrum of each series is characterized by a power-law behaviour at low frequency range, with a ...
