Solving Homogeneous and Heterogeneous Cooperative Tasks with Greedy Sequential Execution

ICLR 2024spotlight

Cooperative multi-agent reinforcement learning (MARL) is extensively used for solving complex cooperative tasks, and value decomposition methods are a prevalent approach for this domain. However, these methods have not been successful in addressing both homogeneous and heterogeneous tasks simultaneo…

True Knowledge Comes from Practice: Aligning Large Language Models with Embodied Environments via Reinforcement Learning

ICLR 2024poster

Despite the impressive performance across numerous tasks, large language models (LLMs) often fail in solving simple decision-making tasks due to the misalignment of the knowledge in LLMs with environments. On the contrary, reinforcement learning (RL) agents learn policies from scratch, which makes t…

Controlling Type Confounding in Ad Hoc Teamwork with Instance-wise Teammate Feedback Rectification

ICML 2023poster

Ad hoc teamwork requires an agent to cooperate with unknown teammates without prior coordination. Many works propose to abstract teammate instances into high-level representation of types and then pre-train the best response for each type. However, most of them do not consider the distribution of te…

Moving Forward in Formation: A Decentralized Hierarchical Learning Approach to Multi-Agent Moving Together

IROS 2021poster

Multi-agent path finding in formation has many potential real-world applications like mobile warehouse robotics. However, previous multi-agent path finding (MAPF) methods hardly take formation into consideration. Further-more, they are usually centralized planners and require the whole state of the…

One-shot Face Reenactment Using Appearance Adaptive Normalization

AAAI 2021technical

The paper proposes a novel generative adversarial network for one-shot face reenactment, which can animate a single face image to a different pose-and-expression (provided by a driving image) while keeping its original appearance. The core of our network is a novel mechanism called appearance adapti…
