SPARK: Self-Correcting Embodied Memory via Physical Re-Observation

Read the original on arXiv Computation and Language →

SPARK is a corrective multi‑episode framework for embodied retrieval‑augmented generation that uses a semantic critic, a targeted planner, and selective merging to refine a knowledge base after each episode. In experiments on four AirSim outdoor maps under degraded viewpoints, a single corrective episode improves embodied question‑answering performance on every map while reducing stored objects by 13–41 %. Extending correction to four episodes surpasses the performance of the undegraded reference on all maps, and ablations confirm the importance of each component.

MemoProAgent: Toward Memory-Driven Proactive Assistance

MemoProAgent tackles memory‑driven proactive assistance by mining long‑horizon personal memories to decide when an assistant should intervene. The authors introduce MemoProBench, a benchmark pairing egocentric video with year‑long, distractor‑rich user memories and human‑verified trigger windows, and show that existing models perform poorly (≤15%). MemoProAgent uses a graph‑organized memory store and a lightweight RL stage to improve accuracy from <10% to 42.4% without training.

When Does Memory Help? A Cost-Aware Evaluation of Long-Term Memory in Tool-Using LLM Agents

The paper introduces MERIT, a benchmark that evaluates the marginal benefit of long‑term memory for tool‑using large language model agents while explicitly accounting for cost. MERIT provides episodic tool‑use tasks across three domains, verifies dependence on earlier‑episode facts, and measures memory operations in tokens and dollars. Experiments on GPT‑4.1‑mini, Claude Haiku 4.5, and Claude Sonnet 5 show that memory can significantly improve task success, but its utility varies widely across models and memory implementations, and full replay is rarely cost‑effective.

ProPerAgent: Toward Memory-Driven Proactive Assistance

The paper introduces ProPerMem, a benchmark for memory-driven proactive assistance that pairs egocentric video with long, distractor-rich personal memories and human-verified trigger windows. Baseline models perform poorly, achieving at most 15% accuracy, while an oracle-driven GPT-5.3-Chat model reaches 96% when given evidence inside the trigger window. Building on these insights, the authors develop ProPerAgent, a plug‑and‑play system that retrieves relevant memory from a graph store and uses lightweight reinforcement learning to improve proactive intervention accuracy to 42.4% without training.
