Large Language Models for Orchestrating Bimanual Robots

no code implementations2 Apr 2024 Kun Chu, Xufeng Zhao, Cornelius Weber, Mengdi Li, Wenhao Lu, Stefan Wermter

Although there has been rapid progress in endowing robots with the ability to solve complex manipulation tasks, generating control policies for bimanual robots to solve tasks involving two hands is still challenging because of the difficulties in effective temporal and spatial coordination.

In-Context Learning Language Modelling

Causal State Distillation for Explainable Reinforcement Learning

1 code implementation30 Dec 2023 Wenhao Lu, Xufeng Zhao, Thilo Fryen, Jae Hee Lee, Mengdi Li, Sven Magg, Stefan Wermter

This lack of transparency in RL models has been a long-standing problem, making it difficult for users to grasp the reasons behind an agent's behaviour.

Enhancing Zero-Shot Chain-of-Thought Reasoning in Large Language Models through Logic

1 code implementation23 Sep 2023 Xufeng Zhao, Mengdi Li, Wenhao Lu, Cornelius Weber, Jae Hee Lee, Kun Chu, Stefan Wermter

Recent advancements in large language models have showcased their remarkable generalizability across various domains.

Causal Inference

A Closer Look at Reward Decomposition for High-Level Robotic Explanations

no code implementations25 Apr 2023 Wenhao Lu, Xufeng Zhao, Sven Magg, Martin Gromniak, Mengdi Li, Stefan Wermter

Explaining the behaviour of intelligent agents learned by reinforcement learning (RL) to humans is challenging yet crucial due to their incomprehensible proprioceptive states, variational intermediate goals, and resultant unpredictability.

Chat with the Environment: Interactive Multimodal Perception Using Large Language Models

1 code implementation14 Mar 2023 Xufeng Zhao, Mengdi Li, Cornelius Weber, Muhammad Burhan Hafez, Stefan Wermter

However, it remains challenging to ground LLMs in multimodal sensory input and continuous action output, while enabling a robot to interact with its environment and acquire novel information as its policies unfold.

Internally Rewarded Reinforcement Learning

1 code implementation1 Feb 2023 Mengdi Li, Xufeng Zhao, Jae Hee Lee, Cornelius Weber, Stefan Wermter

We study a class of reinforcement learning problems where the reward signals for policy learning are generated by an internal reward model that is dependent on and jointly optimized with the policy.

Impact Makes a Sound and Sound Makes an Impact: Sound Guides Representations and Explorations

1 code implementation4 Aug 2022 Xufeng Zhao, Cornelius Weber, Muhammad Burhan Hafez, Stefan Wermter

Sound is one of the most informative and abundant modalities in the real world while being robust to sense without contacts by small and cheap sensors that can be placed on mobile devices.
