Short Bio
Welcome to my personal webpage! My name is Yang Xiao (Chinese: 肖阳). I am currently a Researcher at TikTok. Prior to that, I earned my Master’s degree in Computer Science from Northeastern University, where I was supervised by Ryan Rad. I also hold a Bachelor’s degree from Beihang University.
My research interests mainly focus on 2D computer vision, including but not limited to image classification/detection/segmentation, semi-supervised learning, contrastive learning, human image generation, diffusion model, etc.

Built a pipeline aiming at generating pet images and videos in a personalized and customized way. To better preserve the original pet features, we followed DreamBooth + LoRA paradigm; furthermore, we inserted the LoRA weight into AnimateDiff framework to animate the original pet.

Real-time Interactive Online-Classroom

Course project
code
Built a online classroom where students and teachers can chat and draw some sketches in real-time. The tech stack is based on Typescript, Node.js, React and Redis. To ensure real-time and low-lantency, communication between front-end and back-end was implemented via websocket.
