HiMAP-Travel: Hierarchical Multi-Agent Planning for Long-Horizon Constrained Travel

The Viet Bui, Wenjun Li, Yong Liu

Sequential LLM agents fail on long-horizon planning with hard constraints like budgets and diversity requirements. As planning progresses and context grows, these agents drift from…

Preference-Guided Learning for Sparse-Reward Multi-Agent Reinforcement Learning

The Viet Bui, Tien Mai, Hong Thanh Nguyen

We study the problem of online multi-agent reinforcement learning (MARL) in environments with sparse rewards, where reward feedback is not provided at each interaction but only rev…

MisoDICE: Multi-Agent Imitation from Unlabeled Mixed-Quality Demonstrations

The Viet Bui, Tien Mai, Hong Thanh Nguyen

We study offline imitation learning (IL) in cooperative multi-agent settings, where demonstrations have unlabeled mixed quality - containing both expert and suboptimal trajectories…

O-MAPL: Offline Multi-agent Preference Learning

The Viet Bui, Tien Mai, Hong Thanh Nguyen

Inferring reward functions from demonstrations is a key challenge in reinforcement learning (RL), particularly in multi-agent RL (MARL), where large joint state-action spaces and c…

ComaDICE: Offline Cooperative Multi-Agent Reinforcement Learning with Stationary Distribution Shift Regularization

The Viet Bui, Thanh Hong Nguyen, Tien Mai

Offline reinforcement learning (RL) has garnered significant attention for its ability to learn effective policies from pre-collected datasets without the need for further environm…

Inverse Factorized Q-Learning for Cooperative Multi-agent Imitation Learning

The Viet Bui, Tien Mai, Thanh Hong Nguyen

This paper concerns imitation learning (IL) (i.e, the problem of learning to mimic expert behaviors from demonstrations) in cooperative multi-agent systems. The learning problem un…

Mimicking To Dominate: Imitation Learning Strategies for Success in Multiagent Competitive Games

The Viet Bui, Tien Mai, Thanh Hong Nguyen

Training agents in multi-agent competitive games presents significant challenges due to their intricate nature. These challenges are exacerbated by dynamics influenced not only by…
