Welcome to Yuanhao Pu’s homepage!

Pu Yuanhao is currently a (4th-year) full-time Ph.D. student in School of Artificial Intelligence & Data Science (formerly named as School of Data Science), University of Science and Technology of China (USTC), under the supervison of Prof.Defu Lian. He got his B.S. degree from School of Mathematical Sciences, University of Science and Technology of China (USTC) in Jun. 2021.

His research interest mainly focus on Machine Learning Theories and its applications on Recommender Systems, especially Bayes-Consistency properties for theoretical understandings of model design.
