MemRec: Collaborative Memory for LLM-Based Recommender Systems

other · 2026-04-30

A new framework called MemRec introduces collaborative memory to LLM-based agentic recommender systems, addressing the limitation of isolated semantic memories. By connecting user-item co-engagements and peer relationships across the community, MemRec enables sharing of relational insights to uncover hidden preferences, especially for data-sparse users. The framework decouples memory management from reasoning to avoid context overload and noise. Published on arXiv (2601.08816), the paper proposes a paradigm shift from traditional collaborative filtering to agentic systems enhanced with collaborative memory.
