Welcome to Jiajun Xu’s homepage

Welcome to my homepage!

I am currently a senior student in Tsinghua University, Computer Science and Technology Department.

My research interests lay on machine learning, computer vision and multi-modal.

Specifically, I’m passionate about exploring visual model understanding and visual generation.

My specific research interests are:

• Reinforcement learning for video generation models, manipulating diffusion model noise to get faster and stronger generators.
• Exploring the latent space of transformers and fine-tuning attention to reduce multi-modal hallucinations.
• Exploring the understanding ability of diffusion models.

I have been looking forward to communicating and collaborating with others who share my interests, hoping to work together on interesting projects.

Meanwhile, I expect to graduate in 2026. If you are interested in me, you can check my cv.
