Anirudh Nair

I am currently a CS graduate student at Tufts University advised by Jivko Sinapov. I'm interested in robotics, imitation learning, reinforcement learning, and computer vision.

Previously I was a research scientist in the Complexity Group in the Nuclear Engineering department at UC Berkeley and worked with Bethany Goldblum and Chris Stewart. During my undergraduate studies at UT Austin, I was advised by Xuesu Xiao and Peter Stone and worked on autonomous robot navigation.

blind-date Benchmarking Reinforcement Learning Techniques for Autonomous Navigation
Zifan Xu, Bo Liu, Xuesu Xiao, Anirudh Nair, Peter Stone
IEEE International Conference on Robotics and Automation (ICRA), 2023
Paper

In this paper, we identify four major desiderata of applying deep RL approaches for autonomous navigation: (D1) reasoning under uncertainty, (D2) safety, (D3) learning from limited trial-and-error data, and (D4) generalization to diverse and novel environments. Then, we explore four major classes of learning techniques with the purpose of achieving one or more of the four desiderata: memory-based neural network architectures (D1), safe RL (D2), model-based RL (D2, D3), and domain randomization (D4).

blind-date DynaBARN: Benchmarking Metric Ground Navigation in Dynamic Environments
Anirudh Nair, Fulin Jiang, Kang Hou, Zifan Xu , Shuozhe Li, Xuesu Xiao, Peter Stone
IEEE International Symposium on Safety, Security, and Rescue Robotics (SSRR), 2022
Paper / Website / Dataset / bibtex

In this paper, we present a simulation testbed, DynaBARN, to evaluate a robot navigation system's ability to navigate in environments with obstacles with different motion profiles, which are systematically generated by a set of difficulty metrics.

prl Socially Compliant Navigation Dataset (SCAND): A Large-Scale Dataset of Demonstrations for Social Navigation
Haresh Karnan, Anirudh Nair, Xuesu Xiao, Garrett Warnell, Soeren Pirk, Alexander Toshev, Justin Hart, Joydeep Biswas, Peter Stone
IEEE Robotics and Automation Letters (IEEE RA-L) , 2022
Paper / Website / Video / Poster / Dataset / bibtex

We introduce a large-scale, first-person-view dataset of socially compliant robot navigation demonstrations. SCAND consists of 138 trajectories, 25 miles of socially compliant navigation demonstrations collected on 2 robots by 4 human demonstrators within the UT Austin campus.

blind-date APPLR: Adaptive Planner Parameter Learning from Reinforcement
Zifan Xu, Gauraang Dhamankar, Anirudh Nair, Xuesu Xiao, Garrett Warnell, Bo Liu, Zizhao Wang, Peter Stone
IEEE International Conference on Robotics and Automation (ICRA), 2021
Paper / Website / Video / bibtex

In this paper, we introduce APPLR, Adaptive Planner Parameter Learning from Reinforcement, which allows existing navigation systems to adapt to new scenarios by using a parameter selection scheme discovered via reinforcement learning (RL) in a wide variety of simulation environments.


Yep... it's another Jon Barron website.
