MemDreamer Uses Hierarchical Graph Memory to Decouple Perception From Reasoning in Long Video

arXiv (via HuggingFace Daily Papers)·low signal

MemDreamer (arXiv 2606.07512) separates visual perception from reasoning for long-video understanding using a hierarchical graph memory that compresses scene state so the model can reason over extended footage. It's a useful design pattern for builders working on long-context multimodal memory and agents that consume video.
