Arctic Questions, Missing Answers: A Dataset and Benchmark for LLM Abstention in Arctic Science

Large language models (LLMs) should abstain from scientific multiple-choice questions when no option is valid, but frequent abstention alone does not demonstrate sensitivity to answer availability. We introduce ArcticQA, a dataset of 194 questions derived from primary Arctic research, with automated checks of answer su …

AlignQuant: Tile-Aligned Mixed-Precision Quantization for Efficient LLM Generation

Hanzhi Zhang, Qiao Zhang, Qinglei Cao وآخرون · 2026

Fine-grained mixed-precision quantization promises efficient large language model inference, but local precision choices can conflict with regular GPU storage and computation units. This precision-boundary mismatch limits the translation of compression into practical acceleration. We introduce AlignQuant, a post-traini …

RGBD20K: A Large-Scale Benchmark for RGB-D Semantic Segmentation

Shaohua Dong, Zexuan Meng, Haiyan Sun وآخرون · 2026

In this paper, we propose RGBD20K, a novel dataset for facilitating the development of more robust and general RGB-D semantic segmentation by encompassing abundant categories and high-quality annotations. RGBD20K possesses several attractive properties: (1) Expanded Semantic Space. In particular, it covers 160 fine-gra …
