Personalized Decision Supports based on Theory of Mind Modeling and Explainable Reinforcement Learning

no code implementations13 Dec 2023 Huao Li, Yao Fan, Keyang Zheng, Michael Lewis, Katia Sycara

Our proposed approach is agnostic to task environment and RL model structure, therefore has the potential to be generalized to a wide range of applications.

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

no code implementations16 Oct 2023 Huao Li, Yu Quan Chong, Simon Stepputtis, Joseph Campbell, Dana Hughes, Michael Lewis, Katia Sycara

While Large Language Models (LLMs) have demonstrated impressive accomplishments in both reasoning and planning, their abilities in multi-agent collaborations remains largely unexplored.

Interpretable Learned Emergent Communication for Human-Agent Teams

no code implementations19 Jan 2022 Seth Karten, Mycal Tucker, Huao Li, Siva Kailas, Michael Lewis, Katia Sycara

In human-agent teams tested in benchmark environments, where agents have been modeled using the Enforcers, we find that a prototype-based method produces meaningful discrete tokens that enable human partners to learn agent communication faster and better than a one-hot baseline.

Emergent Discrete Communication in Semantic Spaces

no code implementations NeurIPS 2021 Mycal Tucker, Huao Li, Siddharth Agrawal, Dana Hughes, Katia Sycara, Michael Lewis, Julie Shah

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.

Adaptive Agent Architecture for Real-time Human-Agent Teaming

no code implementations7 Mar 2021 Tianwei Ni, Huao Li, Siddharth Agrawal, Suhas Raja, Fan Jia, Yikang Gui, Dana Hughes, Michael Lewis, Katia Sycara

Previous human-human team research have shown complementary policies in TSF game and diversity in human players' skill, which encourages us to relax the assumptions on human policy.

SpeakingFaces: A Large-Scale Multimodal Dataset of Voice Commands with Visual and Thermal Video Streams

1 code implementation5 Dec 2020 Madina Abdrakhmanova, Askat Kuzdeuov, Sheikh Jarju, Yerbolat Khassanov, Michael Lewis, Huseyin Atakan Varol

We present SpeakingFaces as a publicly-available large-scale multimodal dataset developed to support machine learning research in contexts that utilize a combination of thermal, visual, and audio data streams; examples include human-computer interaction, biometric authentication, recognition systems, domain transfer, and speech recognition.

Predicting Human Strategies in Simulated Search and Rescue Task

no code implementations15 Nov 2020 Vidhi Jain, Rohit Jena, Huao Li, Tejus Gupta, Dana Hughes, Michael Lewis, Katia Sycara

In our efforts to model the rescuer's mind, we begin with a simple simulated search and rescue task in Minecraft with human participants.

Explanation of Reinforcement Learning Model in Dynamic Multi-Agent System

no code implementations4 Aug 2020 Xinzhi Wang, Huao Li, HUI ZHANG, Michael Lewis, Katia Sycara

The results show that verbal explanation generated by both models improve subjective satisfaction of users towards the interpretability of DRL systems.

Transparency and Explanation in Deep Reinforcement Learning Neural Networks

1 code implementation17 Sep 2018 Rahul Iyer, Yuezhang Li, Huao Li, Michael Lewis, Ramitha Sundar, Katia Sycara

For those systems to be accepted and trusted, the users should be able to understand the reasoning process of the system, i. e. the system should be transparent.
