Dr. Deguang Kong is currently a Sr. Research Scientist at  Yahoo Research He previously  worked as a researcher at Samsung Research America, America Los Alamos National Lab and NEC Research Lab Silicon Valley. He has strong interdisciplinary background in machine learning/data mining and cyber security/privacy. He has worked on various research projects, including robust feature learning via structural sparsity, distance learning and label propagation for malware classification, and security-aware mobile app ranking and recommendation, etc. He has published over 20 referred articles in top conferences, including CCS; KDD, ICDM, SDM, WSDM, CIKM; ICML, NIPS, AAAI, ECML/PKDD, CVPR; SIGMETRICS, INFOCOM, etc. He was invited to serve as a reviewer for numerous top conferences and journals, such as KDD, ICDM, SDM, IJCAI, AAAI, TKDE, TNNLS, TIP, TCSVT, TKDD, DMKD, BMC Bioinformatics, and INFOCOM, IEEE transactions on dependable and secure computing (TDSC), IEEE TIFS,  IEEE Systems Journal, Winter Simulation Conference (WSC), CODASPY, SCN, etc.  

Dr. Kong's research spans both data mining/machine learning/big data analytics and cyber security and privacy. He held a Ph.D. in cyber security and privacy under the supervision of Dr. Peng Liu at the Cyber Security Lab Pennsylvania State University from Aug. 2008 to Aug. 2010, and worked on national cyber security projects (supported by DOE) at America Los Alamos National Lab from May 2012 to Dec. 2012. At Samsung Research America, he has been working on mobile cyber security/privacy and data mining/machine learning projects since Jan. 2014. His security paper entitled "SAS: semantic aware signature generation for polymorphic worm detection" was selected as one of three best papers in Securecomm'2010. His research on machine learning algorithms focuses on  robust feature learning and dimension reduction for big data, robust clustering and embedding in presence of noises, etc. His research work at NEC Research Lab Silicon Valley on exclusive feature learning on arbitrary structures was published at NIPS'2014. More information can be found at: Google scholarDBLP, LinkedIN, and Facebook.  His current works focus on big data,  security and privacy, etc.
