STAGE: Structure-Adaptive Graph-Encoded Multi-Agent Policy Gradient for Moving Target Search in Uncertain Topological Networks

ICRA 2026poster

This paper investigates the multi-robot efficient search (MuRES) problem in uncertain topological networks. One unique characteristic of the studied problem is that the topology of the underlying network is uncertain, posing great challenges to canonical MuRES solutions which presumes a fixed networ…

Towards Persistent Noise-Tolerant Active Learning of Regular Languages with Class Query

ICLR 2026poster

Large Language Models (LLMs) are increasingly deployed in human–AI collaborative decision-making systems, where they are expected to align precise formal representations with ambiguous natural language. However, their ad hoc strategies for resolving ambiguity often lead to hallucinations and inconsi…

GoBigger: A Scalable Platform for Cooperative-Competitive Multi-Agent Interactive Simulation

ICLR 2023poster

The emergence of various multi-agent environments has motivated powerful algorithms to explore agents' cooperation or competition. Even though this has greatly promoted the development of multi-agent reinforcement learning (MARL), it is still not enough to support further exploration on the behavio…
