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 […]
