Dr. Yang Song joined Kuaishou (HK.1024) as the Head of Recommendation (VP of Engineering) in June 2020, where he oversees both the core modeling and data mining teams, and later the Search team in 2023. In this role, he managed and lead over 100 engineers and scientists in developing machine learning models that drive Kuaishou’s recommendation, search and advertising engines across all major services, including domestic products (Kuaishou and Kuaishou Express) as well as international products (Kwai). Under his leadership, the platform has emerged as one of the world’s leading short-video content communities and social networks, serving 1 billion monthly active users and experiencing rapid growth (Bloomberg, Forbes). He is also an award-winning researcher, actively involved in organizing academic conferences and has served as Program Committee Chairs and Area Chairs for top conferences such as Recsys, WSDM, TheWebConf (WWW), CIKM, AAAI, ACM-Multimedia and IEEE Big Data.

Prior to joining Kuaishou, Dr. Song served as the Research & Engineering Manager in the Deep Dialogue group of Machine Intelligence at Google AI, where he contributed to developing advanced dialogue engines for Google products through the application of deep learning, natural language processing, and recommender systems.

Dr. Song spent seven years at Microsoft Research (a.k.a. MSR) before joining Google. He worked as a researcher at the Deep Learning Technology Center at Microsoft Research Redmond, Internet Services Research Center (ISRC) and the Search Quality & Cyber-Intelligence Lab (SQ-CIL) at MSR Redmond. He joined Microsoft Research in 2009 following the completion of his Ph.D., during which he collaborated with his advisor, C. Lee Giles, on developing the next-generation scientific literature search engine CiteSeer, which was once one of the world’s most popular scientific literature search engines [screenshot].
