Researchers from Harbin Institute of Technology, The Hong Kong Polytechnic University, and Tianjin University propose a decoupled vision-language reasoning framework, separating visual interpretation from linguistic reasoning. This approach improved accuracy on various multi-modal benchmarks, outperforming LLaVA-CoT-11B by 6.3 percentage points on MathVerse and achieving competitive results with significantly larger models in visually intensive math problems.

Key insights

  • Decoupling visual interpretation from linguistic reasoning allows leveraging the distinct strengths of specialized models, leading to improved performance in complex, visually intensive tasks.
  • Reinforcement learning, when guided by outcome-based rewards, effectively optimizes both the visual interpretation module's description generation and the linguistic reasoning module's problem-solving capabilities.
  • Preprocessing image descriptions to improve conciseness and logical structure significantly enhances the supervised fine-tuning stage and reduces the visual interpretation model's tendency to generate verbose or hallucinated content.
