MemDreamer: Decoupling Perception and Reasoning for Long Video Understanding via Hierarchical Graph Memory and Agentic Retrieval Mechanism

Researchers introduce MemDreamer, a framework that enables Vision-Language Models to process hours-long videos by decoupling perception from reasoning through hierarchical graph memory and agentic retrieval. The approach achieves state-of-the-art results while reducing computational context requirements to 2% of full video ingestion, establishing a new paradigm for long-form multimodal understanding.

Temporal Order Matters for Agentic Memory: Segment Trees for Long-Horizon Agents

Researchers introduce SegTreeMem, a novel memory architecture for long-horizon conversational AI agents that organizes conversation history using temporally-ordered segment trees instead of purely semantic similarity. The system demonstrates improved performance across multiple benchmarks by preserving chronological order while enabling hierarchical retrieval, with ablation studies confirming that temporal sequencing is critical to the approach's effectiveness.
