MRMS: A Multi-Resolution Memory Substrate for Long-Lived AI Agents

Long-lived AI agents require continuity across interactions, but continuity cannot be obtained by simply extending the prompt window. An agent must preserve useful prior experience, retrieve it selectively, distinguish personal context from external evidence, and revise memory when the underlying situation changes.

We propose an architectural memory substrate organized along two orthogonal axes: a representational axis spanning structured records, vector representations, and graph relations; and a temporal axis spanning short-term traces, medium-term abstractions, and long-term semantic commitments. Its key design constraint is synchronized structured-vector-graph memory: structured records govern eligibility, vector representations support recall, and graph relations adjudicate support, contradiction, and supersession before gated context projection. Its central claim is that reliable personalization is a memory design problem: useful memory is structured, selectively exposed, continuously consolidated, and epistemically labeled rather than stored as undifferentiated conversation history.

Beyond the framework, we instantiate MRMS as a lightweight prototype implementing structured records, vector retrieval, temporal policies, and graph-based revision. The prototype exercises the core substrate mechanisms through pre-generation memory selection, revision, boundary enforcement, and evidence attribution under controlled long-lived interaction scenarios with explicit evidence requirements.

Building Memory-Augmented AI Architectures

We design memory-augmented architectural layers for personalised and long-lived human-centric AI systems.

The objective is to develop AI systems that convert user input into personalized knowledge representations that are portable across computational environments, persistent over time, and privately maintained at individual level, while becoming progressively more data-efficient—requiring fewer generic prompts and less new information over time as structured understanding accumulates.

Building long-horizon memory for multimodal conversations

Explores how assistants can retain and retrieve useful experience across extended multimodal sessions — grounding what to store, when to surface it, and how to evaluate continuity without collapsing everything into a raw transcript.

Maintaining revisable user state for long-term personalization

Looks at personalization as an evolving profile problem: using dialogue as evidence for facts, preferences, and slower interaction patterns that can be updated over time rather than treated as static chat history.

Treating multi-session dialogue memory as revisable evidence

Long-term assistants accumulate statements that users later rephrase, correct, soften, or update. Flattened summaries and one-shot fact extraction often merge incompatible claims or keep outdated ones active. This work studies online consolidation of session-derived claims into a persistent memory structure that keeps validity, timing, source, and uncertainty explicit — preserving alternatives when evidence conflicts, and promoting only recurring patterns into longer-lived user memory. We outline evaluation axes for extraction quality, conflict handling, temporal questions, provenance, and cost.

Learning where to retrieve when knowledge spans many sources

Vertical RAG systems often search across websites, uploads, FAQs, and domain collections at once. The hard part is not only ranking passages, but choosing which collections to query — especially in new domains with little labeled routing data. We study a lightweight router that predicts source preference and query intent before search, allocates retrieval budget, and falls back more broadly when confidence is low. Early results suggest learned routing improves source selection, answer quality, and efficiency versus global search and simple heuristics under sparse supervision.
