SpatialCLI: Learning to Reason With Spatial Tools, Then Without Them

Yang Zhou, Zixuan Huang, Sunzhu Li +10

The paper presents SpatialCLI, a framework that teaches vision-language models to use specialist visual tools for spatial reasoning and then internalize those capabilities, dramati…

Breaking the Exploration Bottleneck: Rubric-Scaffolded Reinforcement Learning for General LLM Reasoning

Yang Zhou, Sunzhu Li, Shunyu Liu +11

Recent advances in Large Language Models (LLMs) have underscored the potential of Reinforcement Learning (RL) to facilitate the emergence of reasoning capabilities. Despite the enc…

RubricHub: A Comprehensive and Highly Discriminative Rubric Dataset via Automated Coarse-to-Fine Generation

Sunzhu Li, Jiale Zhao, Miteto Wei +6

Reinforcement Learning with Verifiable Rewards (RLVR) has driven substantial progress in reasoning-intensive domains like mathematics. However, optimizing open-ended generation rem…

Decoding the Ear: A Framework for Objectifying Expressiveness from Human Preference Through Efficient Alignment

Zhiyu Lin, Jingwen Yang, Jiale Zhao +3

Recent speech-to-speech (S2S) models generate intelligible speech but still lack natural expressiveness, largely due to the absence of a reliable evaluation metric. Existing approa…

ThinkPilot: Steering Reasoning Models via Automated Think-prefixes Optimization

Sunzhu Li, Zhiyu Lin, Shuling Yang +2

Large Reasoning Models (LRMs) are powerful, but they still suffer from inefficient and off-target reasoning. Currently, training-free methods are limited to either rigid heuristics…
