Perception or Reasoning? Diagnosing and Tackling Reinforcement Learning Bottlenecks in VLMs

GRAD, a group-relative attention distillation objective that uses the best rollout in each group to directly guide the visual attention of weaker rollouts is proposed, which consistently improves performance across two model scales and seven benchmarks, and further complements existing RL methods.

Multimodal Thinking with Renderable Programs

This work introduces SVGLM, a framework that uses scalable vector graphics (SVG) primitives to connect text and image in reasoning tasks, and exploits the duality of SVG as both image description and text instructions, yielding a more compact, interpretable solution to equip general VLMs with the capability of generati...
