I am a researcher at Huawei Noah's Ark Lab. I obtained my Ph.D. in Computer Science and Engineering from the Chinese University of Hong Kong, supervised by Prof. Pheng Ann Heng. Previously, I was supervised by Prof. Shengyu Zhang. I obtained my B.Eng. degree in computer science and technology from the South China University of Technology in 2016. My research interests include machine learning and algorithms, especially recommender systems.
[HIRING!] I am looking for research interns with strong machine learning and information retrieval background. Please contact liuweiwen8AThuawei.com if you are interested.
