arXiv: Hierarchical Memory Orchestration for Personalized Persistent Agents with User Persona Mapping

arXiv·low signal

A new paper (arXiv:2604.01670) proposes a hierarchical memory system for personalized persistent agents that maintains a compact primary cache coupling recent and pivotal memories with an evolving user profile, complemented by a high-priority secondary layer. Memory redistribution across the hierarchy is dictated by user persona, promoting records mapped to long-term behavioral patterns toward more active tiers. This complements the Omni-SimpleMem and forgetting papers, suggesting April 2026 is producing a cluster of agent memory architecture advances.
