Low-Pass Filtering SGD for Recovering Flat Optima in the Deep Learning Optimization Landscape

Kavli Affiliate: Jing Wang | First 5 Authors: Devansh Bisla, Jing Wang, Anna Choromanska, , | Summary: In this paper, we study the sharpness of a deep learning (DL) loss landscape around local minima in order to reveal systematic mechanisms underlying the generalization abilities of DL models. Our analysis is performed across varying network and […]

High-power laser experiment forming a supercritical collisionless shock in a magnetized uniform plasma at rest

Kavli Affiliate: T. Higuchi | First 5 Authors: Ryo Yamazaki, S. Matsukiyo, T. Morita, S. J. Tanaka, T. Umeda | Summary: We present a new experimental method to generate quasi-perpendicular supercritical magnetized collisionless shocks. In our experiment, ambient nitrogen (N) plasma is at rest and well-magnetized, and it has uniform mass density. The plasma is […]

On the Energy Dependence of Galactic Cosmic Ray Anisotropies in the Very Local Interstellar Medium

Kavli Affiliate: John Richardson | Summary:We report on the energy dependence of galactic cosmic rays (GCRs) in the very local interstellar medium (VLISM) as measured by the Low Energy Charged Particle (LECP) instrument on the Voyager 1 (V1) spacecraft. The LECP instrument includes a dual-ended solid state detector particle telescope mechanically scanning through 360 deg […]

Measurement and simulation of charge diffusion in a small-pixel charge-coupled device

Kavli Affiliate: Gregory Y. Prigozhin | First 5 Authors: Beverly J. LaMarr, Gregory Y. Prigozhin, Eric D. Miller, Carolyn Thayer, Marshall W. Bautz | Summary: Future high-resolution imaging X-ray observatories may require detectors with both fine spatial resolution and high quantum efficiency at relatively high X-ray energies (>5keV). A silicon imaging detector meeting these requirements […]
