XMix: Combating Extremely Noisy Labels via Local Smoothness in Self-Supervised Feature Space

Chengqi Li, Yangdi Lu, Zhihao Shi +3

Supervised deep learning models rely on large, accurately labeled datasets, yet noisy annotations are often unavoidable and can severely degrade performance under high noise levels…

A Maxwell Fish-Eye Lens in a Bose-Einstein Condensate

Jelte Duchêne, Elinor Kath, Floriane Arrouas +7

We experimentally realize an analogue of the optical Maxwell fish-eye lens (MFEL) using phononic excitations in a Bose-Einstein condensate (BEC). A MFEL is characterized by a radia…

Self-Supervised Tree-level Biomass Estimation in Urban Environments From Airborne LiDAR and Optical Observations

Jose Bermudez, Zilong Zhong, Dominic Cyr +2

Urban tree biomass remains less spatially explicitly quantified than biomass in managed forests because many estimates rely on inventories or coarse products that cannot resolve in…
