Structured Graph Network for Constrained Robot Crowd Navigation with Low Fidelity Simulation

no code implementations27 May 2024 Shuijing Liu, Kaiwen Hong, Neeloy Chakraborty, Katherine Driggs-Campbell

We investigate the feasibility of deploying reinforcement learning (RL) policies for constrained crowd navigation using a low-fidelity simulator.

DRAGON: A Dialogue-Based Robot for Assistive Navigation with Visual Language Grounding

1 code implementation13 Jul 2023 Shuijing Liu, Aamir Hasan, Kaiwen Hong, Runxuan Wang, Peixin Chang, Zachary Mizrachi, Justin Lin, D. Livingston McPherson, Wendy A. Rogers, Katherine Driggs-Campbell

Motivated by recent advances in visual-language grounding and semantic navigation, we propose DRAGON, a guiding robot powered by a dialogue system and the ability to associate the environment with natural language.

Occlusion-Aware Crowd Navigation Using People as Sensors

1 code implementation2 Oct 2022 Ye-Ji Mun, Masha Itkina, Shuijing Liu, Katherine Driggs-Campbell

To the best of our knowledge, this work is the first to use social occlusion inference for crowd navigation.

Autonomous Navigation Collision Avoidance

Off Environment Evaluation Using Convex Risk Minimization

1 code implementation21 Dec 2021 Pulkit Katdare, Shuijing Liu, Katherine Driggs-Campbell

We also show that the our method is able to estimate performance of a 7 DOF robotic arm using the simulator and remotely collected data from the robot in the real world.

Reinforcement Learning (RL)

Learning to Navigate Intersections with Unsupervised Driver Trait Inference

1 code implementation14 Sep 2021 Shuijing Liu, Peixin Chang, Haonan Chen, Neeloy Chakraborty, Katherine Driggs-Campbell

Then, we use this trait representation to learn a policy for an autonomous vehicle to navigate through a T-intersection with deep reinforcement learning.

Robust Deep Reinforcement Learning with Adversarial Attacks

no code implementations11 Dec 2017 Anay Pattanaik, Zhenyi Tang, Shuijing Liu, Gautham Bommannan, Girish Chowdhary

This paper proposes adversarial attacks for Reinforcement Learning (RL) and then improves the robustness of Deep Reinforcement Learning algorithms (DRL) to parameter uncertainties with the help of these attacks.
