HingeMem: Revolutionizing Long-Term Memory for Scalable AI Dialogues

HingeMem addresses critical challenges in developing robust, personalized long-term memory for dialogue systems. Traditional methods, reliant on continuous summarization or fixed graph-based retrieval, struggle with adaptability, computational cost, and precise information retrieval. HingeMem, inspired by cognitive neuroscience, proposes a boundary-guided memory architecture that dynamically adapts retrieval based on query type, significantly enhancing performance and efficiency across diverse LLM applications.

Boundary-Guided Long-Term Memory

HingeMem simulates the human brain's cortex and hippocampus to build an interpretable, event-segmented memory. Inspired by Event Segmentation Theory, it draws clear boundaries in dialogues when key elements like person, time, location, or topic change. This reduces redundant operations and preserves salient context, forming structured hyperedges that connect element-specific nodes to concise descriptions.

This approach moves beyond simple textual or fixed graph memories by encoding event boundaries, ensuring fine-grained detail capture and explicit indexing for improved interpretability and query alignment. It constructs a robust memory (M) consisting of element nodes (N), hyperedges (H), and categorized common/rare topics (Ccommon, Crare).

Query-Adaptive Retrieval

HingeMem's innovative retrieval mechanism dynamically determines "what" and "how much" information to retrieve. It generates a query-adaptive retrieval plan that identifies element constraints and priorities (e.g., time > person > location). This contrasts with fixed Top-k retrieval, which often introduces noise or misses crucial information.

Key components include: Hyperedge Reranking, which prioritizes memories based on involved node salience and proximity to rare/common topics, and Adaptive Stopping policies tailored to three query types: Recall-Priority (identifies inflection points), Precision-Priority (uses confidence thresholds), and Judgment (uses softmax scores). This significantly reduces unnecessary token costs and enhances response accuracy.
