Hi, I am Zixu Li (李子旭).
I am a Ph.D. student in Artificial Intelligence at Shandong University, under the supervision of Prof. Liqiang Nie and Prof. Yupeng Hu. In 2023, I received my Bachelor’s degree in Data Science and Big Data Technology from Shandong University.
My research interests include multimedia computing, information retrieval, and approximate nearest neighbor search.
I am a strong advocate for open science. All the projects I have been primarily involved in have been fully open-sourced. We warmly invite you to explore our projects, share your feedback, and connect with us for further discussion.
我是开放科学的坚定拥趸，主要参与的项目均已全面开源。欢迎大家访问我们的项目主页，非常期待听到您的真实反馈，随时欢迎找我交流探讨！
Our open source projects
Here’s the link to our repo! Feel free to check it out. Any feedback or support are always welcome. Thanks for taking a look! ✨
