My research interests focus on LLM agents, deep reinforcement learning, and their applications in decision-making and robotics.

Verlog: A Multi-turn RL framework for LLM agentsL
Wen-Tse Chen, Jiayu Chen, Hao Zhu, Jeff Schneider,

Proposed a multi-turn reinforcement learning framework built for long-horizon LLM-agentic tasks with highly variable episode lengths.

Decentralized Navigation of a Cable-Towed Load using Quadrupedal Robot Team via MARL
Wen-Tse Chen*, Minh Nguyen*, Zhongyu Li*, Guo Ning Sue, Koushil Sreenath

Proposed a scalable, decentralized MARL-based system for coordinating a team of quadrupedal robots to collaboratively tow a cable-connected load through cluttered environments, ensuring flexibility, scalability, and robustness across varying team sizes and environmental conditions.

Fine-tuning LLM Agents with Retrospective In-Context Online Learning
Wen-Tse Chen, Jiayu Chen, Fahim Tajwar, Hao Zhu, Xintong Duan, Russ Salakhutdinov, Jeff Schneider
NeurIPS Adaptive Foundation Models Workshop, 2024 (Oral presentation)

Presented a sample-efficient method for online fine-tuning LLM agents by using in-context learning to convert sparse feedback into dense signals, enabling LLMs to adapt to dynamic environments with minimal data.

DGPO: Discovering Multiple Strategies with Diversity-Guided Policy Optimization
Wen-Tse Chen, Shiyu Huang, Yuan Chiang, Tim Pearce, Wei-Wei Tu, Chen Ting, Zhu Jun,
The 38th Annual AAAI Conference on Artificial Intelligence (AAAI2024)

Proposed an on-policy framework for discovering multiple diverse optimal strategies for the same task in a single training process.
