DREAM：面向多模态多智能体辩论的动态分辨率分配方法
DREAM: Dynamic Resolution Assignment For Multimodal Multi-agent Debate
AI 导读
DREAM 通过动态分辨率分配与不确定性引导回滚聚合两项机制改进多模态多智能体辩论，前者用零样本探测轮结合 ANLL 为每个智能体分配最优分辨率，后者追踪各轮不确定性以恢复被群体压力覆盖的低不确定性答案。在六个多模态数据集上，DREAM 无需针对数据集调参，将准确率- token 权衡较基线提升 1.5-3.2% 准确率。

Abstract:Multi-agent debate (MAD) has emerged as an effective paradigm to improve the reasoning capabilities of large language models (LLMs) and is increasingly being extended to multimodal settings. However, existing multimodal MAD frameworks typically expose agents to the same fixed visual input, ignoring substantial variation in the visual scale needed across samples and agents. In addition, these frameworks frequently suffer from groupthink, a phenomenon where agents prematurely abandon correct deductions to conform with confident but hallucinated peer responses. To address these bottlenecks, we introduce DREAM (Dynamic Resolution Assignment For Multimodal Multi-Agent Debate), which operates via two core components: (1) Dynamic Resolution Assignment, a zero-shot probe round where agents test multiple resolutions, quantify uncertainty using Average Normalized Log-Likelihood (ANLL), and use an adaptive threshold to assign each agent to its empirically optimal resolution; (2) Uncertainty-Guided Rollback Aggregation counters groupthink by tracking each agent's uncertainty over rounds and restoring early low-uncertainty answers overridden by group pressure. On six multimodal datasets, DREAM improves the accuracy-token trade-off over multi-agent debate baselines by 1.5-3.2% accuracy without dataset-specific tuning.
