Intent Demonstration in General-Sum Dynamic Games via Iterative Linear-Quadratic Approximations

no code implementations15 Feb 2024 Jingqi Li, Anand Siththaranjan, Somayeh Sojoudi, Claire Tomlin, Andrea Bajcsy

Autonomous agents should be able to coordinate with other agents without knowing their intents ahead of time.

Adaptive Human Trajectory Prediction via Latent Corridors

no code implementations11 Dec 2023 Neerja Thakkar, Karttikeya Mangalam, Andrea Bajcsy, Jitendra Malik

We formalize the problem of scene-specific adaptive trajectory prediction and propose a new adaptation approach inspired by prompt tuning called latent corridors.

Conformal Decision Theory: Safe Autonomous Decisions from Imperfect Predictions

no code implementations9 Oct 2023 Jordan Lekeufack, Anastasios N. Angelopoulos, Andrea Bajcsy, Michael I. Jordan, Jitendra Malik

We introduce Conformal Decision Theory, a framework for producing safe autonomous decisions despite imperfect machine learning predictions.

Deception Game: Closing the Safety-Learning Loop in Interactive Robot Autonomy

no code implementations3 Sep 2023 Haimin Hu, Zixu Zhang, Kensuke Nakamura, Andrea Bajcsy, Jaime F. Fisac

An outstanding challenge for the widespread deployment of robotic systems like autonomous vehicles is ensuring safe interaction with humans without sacrificing performance.

Learning Vision-based Pursuit-Evasion Robot Policies

no code implementations30 Aug 2023 Andrea Bajcsy, Antonio Loquercio, Ashish Kumar, Jitendra Malik

We find that the quality of the supervision signal for the partially-observable pursuer policy depends on two key factors: the balance of diversity and optimality of the evader's behavior and the strength of the modeling assumptions in the fully-observable policy.

Towards Modeling and Influencing the Dynamics of Human Learning

no code implementations2 Jan 2023 Ran Tian, Masayoshi Tomizuka, Anca Dragan, Andrea Bajcsy

Interestingly, robot actions influence what this experience is, and therefore influence how people's internal models change.

Towards Data-Driven Synthesis of Autonomous Vehicle Safety Concepts

no code implementations30 Jul 2021 Karen Leung, Andrea Bajcsy, Edward Schmerling, Marco Pavone

As safety-critical autonomous vehicles (AVs) will soon become pervasive in our society, a number of safety concepts for trusted AV deployment have recently been proposed throughout industry and academia.

Physical Interaction as Communication: Learning Robot Objectives Online from Human Corrections

no code implementations6 Jul 2021 Dylan P. Losey, Andrea Bajcsy, Marcia K. O'Malley, Anca D. Dragan

We recognize that physical human-robot interaction (pHRI) is often intentional -- the human intervenes on purpose because the robot is not doing the task correctly.

Analyzing Human Models that Adapt Online

no code implementations9 Mar 2021 Andrea Bajcsy, Anand Siththaranjan, Claire J. Tomlin, Anca D. Dragan

This enables us to leverage tools from reachability analysis and optimal control to compute the set of hypotheses the robot could learn in finite time, as well as the worst and best-case time it takes to learn them.

Quantifying Hypothesis Space Misspecification in Learning from Human-Robot Demonstrations and Physical Corrections

no code implementations3 Feb 2020 Andreea Bobu, Andrea Bajcsy, Jaime F. Fisac, Sampada Deglurkar, Anca D. Dragan

Recent work focuses on how robots can use such input - like demonstrations or corrections - to learn intended objectives.

A Hamilton-Jacobi Reachability-Based Framework for Predicting and Analyzing Human Motion for Safe Planning

no code implementations29 Oct 2019 Somil Bansal, Andrea Bajcsy, Ellis Ratner, Anca D. Dragan, Claire J. Tomlin

We construct a new continuous-time dynamical system, where the inputs are the observations of human behavior, and the dynamics include how the belief over the model parameters change.

Learning under Misspecified Objective Spaces

1 code implementation11 Oct 2018 Andreea Bobu, Andrea Bajcsy, Jaime F. Fisac, Anca D. Dragan

Learning robot objective functions from human input has become increasingly important, but state-of-the-art techniques assume that the human's desired objective lies within the robot's hypothesis space.
