Bayesian Post Training Enhancement of Regression Models with Calibrated Rankings

ICLR 2026poster

Accurate regression models are essential for scientific discovery, yet high-quality numeric labels are scarce and expensive. In contrast, rankings (especially pairwise) are easier to obtain from domain experts or artificial intelligence (AI) judges. We introduce Bayesian Enhancement with Calibrated…

Post Hoc Regression Refinement via Pairwise Rankings

NeurIPS 2025poster

Accurate prediction of continuous properties is essential to many scientific and engineering tasks. Although deep-learning regressors excel with abundant labels, their accuracy deteriorates in data-scarce regimes. We introduce RankRefine, a model-agnostic, plug-and-play post-hoc refinement technique…

K-Radar: 4D Radar Object Detection for Autonomous Driving in Various Weather Conditions

NeurIPS 2022accept

Unlike RGB cameras that use visible light bands (384∼769 THz) and Lidars that use infrared bands (361∼331 THz), Radars use relatively longer wavelength radio bands (77∼81 GHz), resulting in robust measurements in adverse weathers. Unfortunately, existing Radar datasets only contain a relatively smal…
