About Me
I am Yibo Wang, a PhD student in Computer Science at Purdue University advised by Professor Jianguo Wang. My current research focuses on enhancing the efficiency and usability of vector databases using machine learning techniques. I received my Bachelor’s degree from Sichuan University, where I worked with Professor Mingjie Tang on applying advanced AI techniques to optimize database performance.
