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 firmly believe in the power of open science. Currently, all the major projects I am involved in are fully open source. Additionally, as a member of the Intelligent Media Research Center (iLearn), all of our lab’s papers and code are open source. Please visit iLearn Lab and feel free to share your valuable feedback.
作为开放科学的坚定拥趸,我致力于将研究成果开源,以促进社区的交流与发展。随时欢迎大家访问与交流探讨!
💻 个人项目: 我主要参与的项目均已全面开源,欢迎访问我们的项目主页,非常期待您的真实反馈(欢迎提出 Issue 或 PR)!
🏫 实验室组织: 我隶属于智能媒体研究中心 (iLearn),实验室的论文代码与相关项目也已悉数开源,欢迎访问 iLearn Lab 并提供宝贵意见。
