MemSteer: Turning User Histories into Supervision for Agent Memory Optimization

Read the original on arXiv AI →

MemSteer transforms unlabeled user histories into question‑answer supervision with supporting evidence, enabling memory‑design optimization for agents. It builds evidence‑grounded answer plans that guide question generation and uses source‑grounded auditing to validate annotations. Experiments on ATM‑Bench and RHELM show that MemSteer‑Opt, which leverages this supervision, outperforms baseline BM25 and improves accuracy without updating model parameters.

Beyond Downstream QA: Rethinking How We Evaluate Agent Memory

The paper critiques current agent memory benchmarks that rely on downstream QA accuracy, arguing they conflate memory correctness with retrieval and generation quality, leading to misleading results. It introduces FEB-30, a new benchmark of 30 fact‑evolution trajectories across six diagnostic categories and three difficulty levels, generated automatically to provide deterministic ground truth. Using FEB-30, the authors show a significant divergence between intrinsic and extrinsic evaluations, revealing that a representative memory system correctly classifies memory operations only 20% of the time—an error invisible to traditional QA metrics.

Learning to Remember: End-to-End Training of Memory Agents for Long-Context Reasoning

The paper introduces the Unified Memory Agent (UMA), a system that builds a query‑agnostic external memory from a data stream and reuses it across multiple question‑answering sessions. UMA employs a single policy to manage a structured Memory Bank via CRUD operations and uses Task‑Stratified GRPO to supervise memory maintenance based on QA trajectory rewards. The authors also present Ledger‑QA, a benchmark for long‑horizon state tracking, and demonstrate that UMA outperforms other methods on test‑time learning and accurate‑retrieval tasks, with UMA‑Specialist further improving performance after task adaptation.

What Should an Agent Forget? Separating What Is Stored from What Is Used

The paper introduces RD-Forget, a training‑free framework that separates what a persistent language agent stores from what it uses at answer time. It keeps a source archive of all observations while a query‑conditioned memory view filters evidence relevant to the current question, using a frozen language‑model curator to group facts into semantic slots and preserve multi‑hop relations. The approach employs rate‑distortion principles to stay within a memory budget and demonstrates improvements across conversational memory, knowledge updating, fact consolidation, long‑context reasoning, and personalization tasks.
