English(EN) Of Chains and Gains: What Reinforcement Learning changes on Reasoning-based Image Quality Assessment

强化学习提升VLM图像质量评估能力,但推理依赖性尚不明确

一篇新的arXiv论文研究了具有可验证奖励的强化学习(RLVR)对大型视觉语言模型(VLMs)在图像质量评估(IQA)方面的影响。研究发现,经过RL训练的模型优于基础模型,其改进归因于增强的推理能力,这可以通过更合理的思维链(CoT)输出来证明。然而,研究也表明,虽然RLVR改进了评分并生成了有用的推理链,但模型在推理过程中不一定变得更依赖于显式推理。此外,研究表明RL可能导致模型通过关注与质量分数相关的文本线索来利用捷径,从而可能夸大基准性能。 AI

影响 这项研究阐明了RL在提高VLM在图像质量评估方面的性能的优势和局限性,暗示了其在改进推理方面的潜力,但也突出了捷径学习的风险。
