My name is Chunpai Wang (王春派). I am a PhD candidate in Computer Science at State University of New York at Albany, where I work on user modeling and sequential recommendation. My thesis advisor is Dr. Sherry Sahebi. During my PhD, I am also fortunate to be advised by Dr. Feng Chen from UT-Dallas and Dr. Daniel B. Neill from NYU on anomaly pattern detection on large-scale graphs. I received a B.S. degree in Computer Science and a B.A. degree in Statistics from the University of Rochester and I was fortunate to be advised by Dr. Jiebo Luo on graph mining research during my undergraduate studies. |

ResearchCurrently, I am mainly working on user modeling and sequential recommendation with applications where users' inherent states are not observable from partially observed data. The title of my working thesis is "Sequential User Modeling and Recommendation Under Partially Obeservable Environment". I am also working on counterfactual evaluation and model-based reinforcement learning that are related to offline evaluation of long-term and delayed rewards of sequential recommendation policies. Besides, I am also interested in and have been working on anomaly pattern detection in images and graphs. Overall, I have 6 years hand-on experience on doing research independently and collaboratively, including identifing the nature of a problem, conducting literurature reviews, statistical modeling, rigorous experimental design and result analysis. Following is a list of my publications. |
