Representation Learning and More
P.S. we have another group led by A/Prof. Xin Li working on data mining, (deep) representation learning with applications to healthcare, social network analysis and recommender systems. We are also recruiting students to work on the related fields every year. For more details, please go to Xin's homepage@BIT. Here's our selected publications.
