Thinking with Blueprints: Assisting Vision-Language Models in Spatial Reasoning via Structured Object Representation

Weijian Ma, Shizhao Sun, Tianyu Yu +3

Spatial reasoning -- the ability to perceive and reason about relationships in space -- advances vision-language models (VLMs) from visual perception toward spatial semantic unders…

Process Reinforcement through Implicit Rewards

Ganqu Cui, Lifan Yuan, Zefan Wang +22

Dense process rewards have proven a more effective alternative to the sparse outcome-level rewards in the inference-time scaling of large language models (LLMs), particularly in ta…
