Short Message Service text messages are indispensable, but they face a serious problem from spamming. This service-side solution uses graph data mining to distinguish spammers from nonspammers and detect spam without checking a message's contents.
Bridging Domains Using World Wide Knowledge for Transfer Learning
IEEE Transactions on Knowledge and Data Engineering
By Evan Wei Xiang, Bin Cao, Derek Hao Hu, Qiang Yang
Issue Date:June 2010
A major problem of classification learning is the lack of ground-truth labeled data. It is usually expensive to label new data instances for training a model. To solve this problem, domain adaptation in transfer learning has been proposed to classify targe...
Constrained collective matrix factorization
Found in: Proceedings of the sixth ACM conference on Recommender systems (RecSys '12)
By Evan Wei Xiang, Rong Pan, Yu-Jia Huang
Issue Date:September 2012
Transfer learning for collaborative filtering (TLCF) aims to solve the sparsity problem by transferring rating knowledge across multiple domains. Taking domain difference into ac- count, one of the issues in cross-domain collaborative filtering is to selec...
PQC: personalized query classification
Found in: Proceeding of the 18th ACM conference on Information and knowledge management (CIKM '09)
By Bin Cao, Derek Hao Hu, Evan Wei Xiang, Jian-Tao Sun, Qiang Yang, Zheng Chen
Issue Date:November 2009
