Explainable Action Advising for Multi-Agent Reinforcement Learning

ICRA 2023poster

Action advising is a knowledge transfer technique for reinforcement learning based on the teacher-student paradigm. An expert teacher provides advice to a student during training in order to improve the student's sample efficiency and policy performance. Such advice is commonly given in the form of…

Theory of Mind for Multi-Agent Collaboration via Large Language Models

EMNLP 2023long main

While Large Language Models (LLMs) have demonstrated impressive accomplishments in both reasoning and planning, their abilities in multi-agent collaborations remains largely unexplored. This study evaluates LLM-based agents in a multi-agent cooperative text game with Theory of Mind (ToM) inference t…

Concept Learning for Interpretable Multi-Agent Reinforcement Learning

CoRL 2022poster

Multi-agent robotic systems are increasingly operating in real-world environments in close proximity to humans, yet are largely controlled by policy models with inscrutable deep neural network representations. We introduce a method for incorporating interpretable concepts from a domain expert into m…

Emergent Discrete Communication in Semantic Spaces

NeurIPS 2021poster

Neural agents trained in reinforcement learning settings can learn to communicate among themselves via discrete tokens, accomplishing as a team what agents would be unable to do alone. However, the current standard of using one-hot vectors as discrete communication tokens prevents agents from acquir…

Recognizing social touch gestures using recurrent and convolutional neural networks

ICRA 2017poster

Deep learning approaches have been used to perform classification in several applications with high-dimensional input data. In this paper, we investigate the potential for deep learning for classifying affective touch on robotic skin in a social setting. Three models are considered, a convolutional…
