English(EN) A Broader Look into MLLM's Retrieval Heads

MLLM检索头是稀疏的、跨模态共享的、可优化的

研究人员调查了多模态大语言模型(MLLM)中的检索头,发现这些负责在长输入中定位相关信息的检索头保持稀疏,并且在视觉和音频等不同模态之间基本共享。他们对18个检查点的研究表明,这些共享的检索头虽然占所有检索头的不到2%,但对于包括文档理解和空间感知在内的任务至关重要。通过使用排序目标来优化这些检索头,研究人员在MMDocIR基准测试上将Qwen3 VL 8B的性能提高了6个多点,证明了它们作为增强MLLM能力的分析工具和优化目标的潜力。 AI

影响 揭示了MLLM中可以针对其进行跨模态性能改进的关键架构组件。
