I am a Master's student at UC Berkeley, graduating in 2023. I am advised by Pieter Abbeel, Youngwoon Lee, and Stephen James at BAIR.

Previously, I graduated from UC Berkeley with a BA in Applied Math and BA in Computer Science.

I'm interested in robot learning. In particular, I would like to build intelligent, adaptable, multi-purpose robots that can learn quickly and accomplish complex tasks. I've worked on a variety of projects in deep reinforcement learning, unsupervised reinforcement learning, and generative graphics to this aim.

vectorfusion VectorFusion: Text-to-SVG by Abstracting Pixel-Based Diffusion Models
Ajay Jain*, Amber Xie*, Pieter Abbeel
CVPR 2023 The IEEE/CVF Conference on Computer Vision and Pattern Recognition, 2023
paper / website / gallery

VectorFusion generates infinitely scalable vector graphics (SVGs), pixel art and sketches from text using the pretrained Stable Diffusion model.

IRM Skill-Based Reinforcement Learning with Intrinsic Reward Matching
Ademi Adeniji*, Amber Xie*, Pieter Abbeel
arXiv 2022
paper / code

IRM leverages the skill discriminator from unsupervised RL pretraining to perform environment-interaction-free skill sequencing for unseen downstream tasks.

Segmentations are a concise, compressed representation for images. We show sim-to-real transfer through training an RL agent on image segmentations for off-road autonomous driving.

maugs Math Augmentation: How Authors Enhance the Readability of Formulas using Novel Visual Design Practices
Andrew Head, Amber Xie, Marti Hearst
CHI 2022 ACM Conference on Human Factors in Computing Systems, 2022
paper / video

We describe how authors alter the presentation of math formulas to make them more approachable, from colorization to labels, layout, and beyond.
