JUST-IN-TIME EPISODIC FEEDBACK HINTER: LEVER-AGING OFFLINE KNOWLEDGE TO IMPROVE LLM AGENTS ADAPTATION
Overview
Paper Summary
This paper introduces JEF HINTER, an agentic system that distills offline trajectories (both successful and failed) into concise, context-aware hints for large language model (LLM) agents. It significantly improves LLM agent performance on web-based tasks by identifying critical decision points and converting them into natural-language guidance. Experiments show JEF HINTER consistently outperforms strong baselines, including human- and document-based hints, without requiring model fine-tuning.
Explain Like I'm Five
This paper teaches AI robots to get better at doing tasks on the computer by giving them smart tips, like 'cheat codes,' learned from all their past attempts, whether they succeeded or failed. It's like a memory for AI to learn from.
Possible Conflicts of Interest
Several authors are affiliated with ServiceNow Research. The paper evaluates performance on WorkArena-L1, a benchmark of enterprise knowledge-work tasks, and references ServiceNow documentation. This constitutes a conflict of interest, as company employees are researching and developing methods that could directly benefit their employer's products and services.
Identified Limitations
Rating Explanation
The paper presents a solid methodology for improving LLM agents with generated hints, demonstrating clear performance gains over strong baselines across multiple benchmarks. The approach of leveraging both successful and failed trajectories and a 'zooming' mechanism is innovative. However, the identified conflict of interest with ServiceNow and the acknowledged computational trade-offs slightly reduce its impact from a top-tier rating.
