Outracing Champion Gran Turismo Drivers with Deep Reinforcement Learning

Nature, 2022
Pete Wurman, Samuel Barrett, Kenta Kawamoto, James MacGlashan, Kaushik Subramanian, Thomas J. Walsh, Roberto Capobianco, Alisa Devlic, Franziska Eckert, Florian Fuchs, Leilani Gilpin, Piyush Khandelwal, Varun Kompella, Hao Chih Lin, Patrick MacAlpine, Declan Oller, Takuma Seno, Craig Sherstan, Michael D. Thomure, Houmehr Aghabozorgi, Leon Barrett, Rory Douglas, Dion Whitehead Amago, Peter Dürr, Peter Stone, Michael Spranger, Hiroaki Kitano

Many potential applications of artificial intelligence involve making real-time decisions in physical systems while interacting with humans. Automobile racing represents an extreme example of these conditions; drivers must execute complex tactical manoeuvres to pass or block…

Jointly Improving Parsing and Perception for Natural Language Commands through Human-Robot Dialog

IJCAIJAIR, 2021
Jesse Thomason*, Aishwarya Padmakumar*, Jivko Sinapov*, Nick Walker*, Yuqian Jiang*, Harel Yedidsion*, Justin Hart*, Peter Stone, Raymond J. Mooney*

In this work, we present methods for using human-robot dialog to improve language understanding for a mobile robot agent. The agent parses natural language to underlying semantic meanings and uses robotic sensors to create multi-modal models of perceptual concepts like red a…

Agent-Based Markov Modeling for Improved COVID-19 Mitigation Policies

JAIR, 2021
Roberto Capobianco, Varun Kompella, James Ault*, Guni Sharon*, Stacy Jong*, Spencer Fox*, Lauren Meyers*, Pete Wurman, Peter Stone

The year 2020 saw the covid-19 virus lead to one of the worst global pandemics in history. As a result, governments around the world have been faced with the challenge of protecting public health while keeping the economy running to the greatest extent possible. Epidemiologi…

Efficient Real-Time Inference in Temporal Convolution Networks

ICRA, 2021
Piyush Khandelwal, James MacGlashan, Pete Wurman, Peter Stone

It has been recently demonstrated that Temporal Convolution Networks (TCNs) provide state-of-the-art results in many problem domains where the input data is a time-series. TCNs typically incorporate information from a long history of inputs (the receptive field) into a singl…

Multiagent Epidemiologic Inference through Realtime Contact Tracing

AAMAS, 2021
Guni Sharon*, James Ault*, Peter Stone, Varun Kompella, Roberto Capobianco

This paper addresses an epidemiologic inference problem where, given realtime observation of test results, presence of symptoms,and physical contacts, the most likely infected individuals need to be inferred. The inference problem is modeled as a hidden Markovmodel where inf…

Expected Value of Communication for Planning in Ad Hoc Teamwork

AAAI, 2021
William Macke*, Reuth Mirsky*, Peter Stone

A desirable goal for autonomous agents is to be able to coordinate on the fly with previously unknown teammates. Known as "ad hoc teamwork", enabling such a capability has been receiving increasing attention in the research community. One of the central challenges in ad hoc …

Temporal-Logic-Based Reward Shaping for Continuing Reinforcement Learning Tasks

AAAI, 2021
Yuqian Jiang*, Sudarshanan Bharadwaj*, Bo Wu*, Rishi Shah*, Ufuk Topcu*, Peter Stone

In continuing tasks, average-reward reinforcement learning may be a more appropriate problem formulation than the more common discounted reward formulation. As usual, learning an optimal policy in this setting typically requires a large amount of training experiences. Reward…

Goal Blending for Responsive Shared Autonomy in a Navigating Vehicle

AAAI, 2021
Yu-Sian Jiang*, Garrett Warnell*, Peter Stone

Human-robot shared autonomy techniques for vehicle navigation hold promise for reducing a human driver's workload, ensuring safety, and improving navigation efficiency. However, because typical techniques achieve these improvements by effectively removing human control at cr…

A Penny for Your Thoughts: The Value of Communication in Ad Hoc Teamwork

IJCAI, 2021
Reuth Mirsky*, William Macke*, Andy Wang*, Harel Yedidsion*, Peter Stone

In ad hoc teamwork, multiple agents need to collaborate without having knowledge about their teammates or their plans a priori. A common assumption in this research area is that the agents cannot communicate. However, just as two random people may speak the same language, au…

Balancing Individual Preferences and Shared Objectives in Multiagent Reinforcement Learning

IJCAI, 2021
Ishan Durugkar*, Elad Liebman*, Peter Stone

In multiagent reinforcement learning scenarios, it is often the case that independent agents must jointly learn to perform a cooperative task. This paper focuses on such a scenario in which agents have individual preferences regarding how to accomplish the shared task. We co…

Firefly Neural Architecture Descent: a General Approach for Growing Neural Networks

NeurIPS, 2020
Lemeng Wu*, Bo Liu*, Peter Stone, Qiang Liu*

We propose firefly neural architecture descent, a general framework for progressively and dynamically growing neural networks to jointly optimize the networks' parameters and architectures. Our method works in a steepest descent fashion, which iteratively finds the best netw…

An Imitation from Observation Approach to Transfer Learning with Dynamics Mismatch

NeurIPS, 2020
Siddharth Desai*, Ishan Durugkar*, Haresh Karnan*, Garrett Warnell*, Josiah Hanna*, Peter Stone

We examine the problem of transferring a policy learned in a source environment to a target environment with different dynamics, particularly in the case where it is critical to reduce the amount of interaction with the target environment during learning. This problem is par…

Reinforcement Learning for Optimization of COVID-19 Mitigation Policies

AAAI AI for Social Good, 2020
Varun Kompella, Roberto Capobianco, Stacy Jong*, Jonathan Browne*, Spencer Fox*, Lauren Meyers*, Pete Wurman, Peter Stone

The year 2020 has seen the COVID-19 virus lead to one of the worst global pandemics in history. As a result, governments around the world are faced with the challenge of protecting public health, while keeping the economy running to the greatest extent possible. Epidemiologi…
