Text-to-Distribution Prediction with Quantile Tokens and Neighbor Context

Yilun Zhu, Yuan Zhuang, Nikhita Vedula +6

Many applications of LLM-based text regression require predicting a full conditional distribution rather than a single point value. We study distributional regression under empiric…

CodeV: Code with Images for Faithful Visual Reasoning via Tool-Aware Policy Optimization

Xinhai Hou, Shaoyuan Xu, Manan Biyani +4

Agentic vision-language models are increasingly trained to "think with images" by calling image operations. However, we show that high final-answer accuracy often hides unfaithful…
