Ph.D. Student in KU MLV Lab Agentic AI

Joined January 2023
I'm in team matching for @Google's Summer 2027 Research Intern position! I build reliable & safe multi-agent LLM systems and work on automated research agents. Open to related topics as well as new directions! Potential hosts, let's connect! DMs/emails welcome; reposts very much appreciated 🙏 ==========More about me========== 🌐 Homepage: froilanchoi.com 📄 CV: drive.google.com/file/d/19og… ✉️ email: [email protected] =============================== #Google #GoogleResearch #ResearchInternship #LLMAgents #MultiAgentSystems #AIResearch

💡 Millions of shared skills. Why should agents keep starting from scratch? Excited to share RASO! 🚀 Retrieve shared skill knowledge, adapt it to the target harness, and use it for rollout-free initialization and feedback-driven updates. #AgenticAI #Skill #Harness

5/5 🛰️ → 📊 From satellite imagery to spreadsheets A retrieved imagery skill handles empty groups before aggregation. Adapting this procedure helps a spreadsheet agent leave missing results blank and avoid shifting values into the wrong rows. Useful knowledge can cross domains
31
4/5 📈 Performance Across 4 benchmarks × 2 LLMs, RASO outperforms TextGrad, GEPA, SkillOpt, and WikiSkill, averaged over 3 seeds. Gains over the strongest competing baseline reach +6.31 pp on SpreadsheetBench and +11.30 pp on WebShop.

3/5 🔧 Cross-Harness Adaptation Relevant knowledge may come from skills written for entirely different tools and environments. We extract the transferable procedure and re-express it using the target harness’s tools, objects, and constraints.

2/5 🔄 RASU: Retrieval-Augmented Skill Update Observing a failure doesn’t always tell you how to fix it. RASU uses failed trajectories to guide retrieval, bringing external knowledge into iterative skill refinement alongside execution feedback.

1/5 🚀 RASI: Retrieval-Augmented Skill Initialization Why wait for expensive rollouts to build a useful skill? RASI retrieves procedural knowledge using only task and harness descriptions, then adapts and combines it into an initial skill—with zero agent rollouts.
