OSWorld-Science: A Benchmark of Computer Use Agents for Learning and Using Scientific Software

Scientific software presents a demanding test for computer-using agents based on visual language models (VLMs): completing a research workflow requires interpreting specialized interfaces, manipulating scientific objects, and producing verifiable results. We thus introduce OSWorld-Science, a benchmark and evaluation en...

NOVA: NOise-aware Verbal Confidence CAlibration for Robust Large Language Models in RAG Systems

Noise-Aware Verbal Confidence CAlibration Rules are proposed to provide a principled foundation for resolving overconfidence under noise and NOVA, a noise-aware calibration framework that synthesizes supervision from ~2K HotpotQA examples guided by these rules.

Farther the Shift, Sparser the Representation: Analyzing OOD Mechanisms in LLMs

This study provides new mechanistic insights into how LLMs internalize OOD challenges, and designs Sparsity-Guided Curriculum In-Context Learning (SG-ICL), a strategy that explicitly uses representation sparsity to schedule few-shot demonstrations, leading to considerable performance enhancements.

Occamy-1.0: Open Pareto-frontier 35B Intelligence for Co-work

Occamy-1.0, a cost-efficient co-work model obtained by further training the post-trained Qwen3.6-35B-A3B checkpoint, is presented and placed at the low-cost knee of the observed cost--performance Pareto frontier.

Finding the Right Tables and Columns: A Benchmark and Corpus-Adaptive Embeddings for SQL Schema Retrieval

This work recast five text-to-SQL datasets as retrieval tasks at both table and column granularity, covering realistic and enterprise-scale schemas under two document representations, and proposes corpus-adaptive fine-tuning, establishing schema linking as a standalone retrieval task and lightweight, label-free corpus...
