ReMAP: Restoring the Perceptual Cycle with Reasoning-Time Latent Visual Memory

Hao Jiang, Zhanyu Guo, Chenwei Wu et al. · 2026

As multimodal large language models (MLLMs) reason for longer, attention to the initial visual input diminishes, weakening visual grounding. Visual memory reintroduces visual evidence during reasoning. We conduct a controlled analysis of visual memory along three axes: curation, organization, and access. We find that l …

MiCo: Mutual Information Coverage Optimization through Semantic Erasure Modeling for Efficient MLLM Inference

Tinghao Wang, Yichen Guo, Qizhe Zhang et al. · 2026

Multimodal large language models (MLLMs) have demonstrated impressive performance in multimodal understanding, but processing large numbers of visual tokens results in high computational costs. While many methods have been proposed to reduce the number of visual tokens, most of them rely on heuristics and are prone to …
