On double-descent in uncertainty quantification in overparametrized models

Florent Gérard Krzakala, Lenka Zdeborová, Lucas Andry Clarte, Bruno Loureiro, Bruno Loureiro

Uncertainty quantification is a central challenge in reliable and trustworthy machine learning. Naive measures such as last-layer scores are well-known to yield overconfident estimates in the context of overparametrized neural networks. Several methods, ra ...

Calibration Transfer Methodology for Cloud Radars Based on Ice Cloud Observations

Alexis Berne

This article presents a calibration transfer methodology that can be used between radars of the same or dif-ferent frequency bands. This method enables the absolute calibration of a cloud radar by transferring it from another collocated instrument with kno ...

Information content and aerosol property retrieval potential for different types of in situ polar nephelometer data

Alireza Moallemi, Robin Lewis Modini, Philippe Giaccari

Polar nephelometers are in situ instruments used to measure the angular distribution of light scattered by aerosol particles. These types of measurements contain substantial information about the properties of the aerosol being probed (e.g. concentrations, ...

Optical measurement method for mechanical time base characterization

Simon Nessim Henein, Etienne Frédéric Gabriel Thalmann

The recent adoption of silicon components by the mechanical watch industry has triggered the search for new time bases to advantageously replace the traditional balance and hairspring oscillator. In particular, flexure-based oscillators manufactured in sil ...

Experimental study of wakefields driven by a self-modulating proton bunch in plasma

Yiming Li, Ambrogio Fasoli, Ivo Furno, Patrick Blanchard, Alan Howling, Yanis Andrebe, Rémy Jacquier, Riccardo Agnello, Sun Hee Kim, Ishkhan Gorgisyan, Shuai Liu

We study experimentally the longitudinal and transverse wakefields driven by a highly relativistic proton bunch during self-modulation in plasma. We show that the wakefields' growth and amplitude increase with increasing seed amplitude as well as with the ...

Un nouveau 'Guide du logement à loyer modéré'

Philippe Thalmann

La Commission fédérale du logement a initié, en 2017, la rédaction d'un glossaire du logement à loyer abordable. Il n'a pas vu le jour, trop grandes étaient les divergences sur les termes. A la place, ce Guide présente différentes vues sur l'habitat bon ma ...

Teaching Measurement Fundamentals

Guglielmo Frigo

While it has always been true that measurements are made to guide decision-making, there is abundant evidence that not all measurement results are meaningful. We give examples of fully-functional, tested and trusted measurement systems producing nonsensica ...

High density fiber postitioner system for massive spectroscopic surveys

Hannes Bleuler, Jean-Paul Richard Kneib, Mohamed Bouri, Luzius Gregor Kronig, Philipp Hörler

We describe here a novel design of a fast high-density robotized fiber positioner system for massive spectroscopic surveys. The fiber positioners are compact, robust, and they can be coordinated, allowing for a high spatial density. Furthermore, the high a ...

Guidance, Navigation and Control for Autonomous Cooperative Docking of CubeSats

Volker Gass, Pierre-Alain Mäusli, Camille Sébastien Pirat

Is it possible to dock CubeSats in Low Earth Orbit? The challenges are mainly associated with the level of miniaturisation. A docking mechanism was designed, built and tested in the laboratory. Results show that a relative precision better than 1 cm and 2 ...
