Pi-DUAL: Using Privileged Information to Distinguish Clean from Noisy Labels

Kavli Affiliate: Ke Wang | First 5 Authors: Ke Wang, Guillermo Ortiz-Jimenez, Rodolphe Jenatton, Mark Collier, Efi Kokiopoulou | Summary: Label noise is a pervasive problem in deep learning that often compromises the generalization performance of trained models. Recently, leveraging privileged information (PI) — information available only during training but not at test time — […]

GPI 2.0: Performance Evaluation of the Wavefront Sensor’s EMCCD

Kavli Affiliate: Bruce Macintosh | First 5 Authors: , , , , | Summary: The Gemini Planet Imager (GPI) is a high contrast imaging instrument that aims to detect and characterize extrasolar planets. GPI is being upgraded to GPI 2.0, with several subsystems receiving a re-design to improve the instrument’s contrast. To enable observations on […]

Divide-and-Conquer Dynamics in AI-Driven Disempowerment

Kavli Affiliate: Max Tegmark | First 5 Authors: Peter S. Park, Max Tegmark, , , | Summary: AI companies are attempting to create AI systems that outperform humans at most economically valuable work. Current AI models are already automating away the livelihoods of some artists, actors, and writers. But there is infighting between those who […]

Testing MURaM and MPS-ATLAS against the quiet solar spectrum

Kavli Affiliate: Robert Cameron | First 5 Authors: Veronika Witzke, Alexander I. Shapiro, Nadiia M. Kostogryz, Lucien Mauviard, Tanayveer S. Bhatia | Summary: Three-dimensional (3D) radiative magnetohydrodynamics (MHD) simulations are the only way to model stellar atmospheres without any ad hoc parameterisations. Several 3D radiative MHD codes have achieved good quantitative agreement with observables for […]
