Image About Me

Dr. Guibing Guo is a Professor in the Software College, Northeastern University, Shenyang, China. He received a Ph.D degree in computer science at Nanyang Technological University, under the supervision of Dr. Jie Zhang and Dr. Daniel Thalmann. Then, he did a post-doc with Dr. Feida Zhu as a research fellow at Singapore Management University.

His research interests include recommender systems, deep learning, social network analysis and data mining. The main research focus is to resolve the challenges of recommender systems, including data sparsity, cold start, diversity and so on. He is the original author (and now the team leader) of the open-source library for recommender systems, LibRec, which implements a large number (over 90) of recommender algorithms. We advocate the sharing and open-source of recommender algorithms, and encourage algorithm authors to contribute their codes to LibRec.

I am very open to research collaboration, and welcome Ph.D students to exchange and join my research team.

For those (self-motivated) students who are interested in recommender systems, drop me an email to discuss more!
