DECOR: Learning to Decompose and Collaborate in Deep Search via Multi-Agent Reinforcement Learning

ICML 2026poster

Monolithic agents in deep search often suffer from "cognitive overload," while existing multi-agent approaches mostly rely on frozen models that cannot learn from collaboration failures. To bridge this gap, we propose $\textbf{DECOR}$ ($\textbf{DE}$compose and $\textbf{CO}$llaborate via $\textbf{R}$…

An LLM-driven Framework for Multiple-Vehicle Dispatching and Navigation in Smart City Landscapes

ICRA 2024poster

In the context of smart cities, autonomous vehicles, such as unmanned delivery vehicles and taxis are gradually gaining acceptance. However, their application scenarios remain significantly fragmented. Typically, an Autonomous Multi-Functional Vehicle (AMFV) is not engaged in other scenarios when id…

Language and Sketching: An LLM-driven Interactive Multimodal Multitask Robot Navigation Framework

ICRA 2024poster

The socially-aware navigation system has evolved to adeptly avoid various obstacles while performing multiple tasks, such as point-to-point navigation, human-following, and -guiding. However, a prominent gap persists: in Human-Robot Interaction (HRI), the procedure of communicating commands to robot…

Off-Agent Trust Region Policy Optimization

IJCAI 2024poster

Leveraging the experiences of other agents offers a powerful mechanism to enhance policy optimization in multi-agent reinforcement learning (MARL). However, contemporary MARL algorithms often neglect experience sharing possibilities or adopt a simple approach via direct parameter sharing. Our work e…

Trust Region Policy Optimisation in Multi-Agent Reinforcement Learning

ICLR 2022poster

Trust region methods rigorously enabled reinforcement learning (RL) agents to learn monotonically improving policies, leading to superior performance on a variety of tasks. Unfortunately, when it comes to multi-agent reinforcement learning (MARL), the property of monotonic improvement may not simpl…
