Xinran Liang

I am a second year PhD student in Computer Science at Princeton University, advised by Olga Russakovsky.

Previously, I received my bachelor degree in Applied Mathematics and Data Science from UC Berkeley. I did research as part of Berkeley Artificial Intelligence Research, where I was advised by Kimin Lee, Aditi Raghunathan, and Pieter Abbeel.

I'm currently working on computer vision and deep reinforcement learning.

ALP: Action-Aware Embodied Learning for Perception
Xinran Liang, Anthony Han, Wilson Yan, Aditi Raghunathan, Pieter Abbeel
arxiv preprint, 2023
paper / website / code

An embodied learning framework based on active exploration for visual representations and perception tasks. We propose to learn representations from action signals implicitly through reinforcement learning and explicitly via inverse dynamics prediction.

Reward Uncertainty for Exploration in Preference-based Reinforcement Learning
Xinran Liang, Katherine Shu, Kimin Lee*, Pieter Abbeel*
International Conference on Learning Representations (ICLR), 2022
paper / code

We propose a simple and efficient human-guided exploration method by measuring uncertainty in human instructions as intrinsic rewards.
