Scalable and Memory-Efficient Clustering of Large-Scale Social Networks
Found in: 2012 IEEE 12th International Conference on Data Mining (ICDM)
By Joyce Jiyoung Whang,Xin Sui,Inderjit S. Dhillon
Issue Date:December 2012
pp. 705-714
Clustering of social networks is an important task for their analysis, however, most existing algorithms do not scale to the massive size of todayâs social networks. A popular class of graph clustering algorithms for large-scale networks, such a...
 
Illegal Information Flow Detection in Electronic Institution
Found in: Genetic and Evolutionary Computing, International Conference on
By Guoyong Cai, Lei Shi, Xin Sui
Issue Date:October 2009
pp. 240-243
Due to the lack of information flow control mechanism, the authorization model of an electronic institution (EI) may bring illegal information propagation threatening the confidentiality of sensitive data. By analyzing information flows among roles, algori...
 
Research on the model of Integration with Semantic Web and Agent Personalized Recommendation System
Found in: International Conference on Computer Supported Cooperative Work in Design
By Xin Sui, Suozhu Wang, Zhaowei Li
Issue Date:April 2009
pp. 233-237
To overcome the disadvantages of the existing recommender system such as intelligence, adaptive, flexibility ability and the limitations of accuracy and efficiency for the results, the framework model of Integration with Semantic Web and Agent Personalized...
 
An Adaptive Bidding Strategy in Multi-round Combinatorial Auctions for Resource Allocation
Found in: Tools with Artificial Intelligence, IEEE International Conference on
By Xin Sui, Ho-Fung Leung
Issue Date:November 2008
pp. 423-430
Combinatorial auctions, where bidders are allowed to put bids on bundles of items, are preferred to single-item auctions in the resource allocation problem because they allow bidders to express complementarities (substitutabilities) among items and therefo...
 
Building Domain Ontology Based on Web Data and Generic Ontology
Found in: Web Intelligence, IEEE / WIC / ACM International Conference on
By Jie Yang, Lei Wang, Song Zhang, Xin Sui, Ning Zhang, Zhuoqun Xu
Issue Date:September 2004
pp. 686-689
The automatic or semi-automatic construction of ontology has become a research topic of interest in recent years. This paper describes a mechanism for constructing domain specific ontologies automatically based on web data and generic ontology. Firstly, we...
 
Exploiting the commutativity lattice
Found in: Proceedings of the 32nd ACM SIGPLAN conference on Programming language design and implementation (PLDI '11)
By Dimitrios Prountzos, Donald Nguyen, Keshav Pingali, Milind Kulkarni, Xin Sui
Issue Date:June 2011
pp. 123-128
Speculative execution is a promising approach for exploiting parallelism in many programs, but it requires efficient schemes for detecting conflicts between concurrently executing threads. Prior work has argued that checking semantic commutativity of metho...
     
The tao of parallelism in algorithms
Found in: Proceedings of the 32nd ACM SIGPLAN conference on Programming language design and implementation (PLDI '11)
By Andrew Lenharth, Dimitrios Prountzos, Donald Nguyen, Keshav Pingali, M. Amber Hassaan, Mario Mendez-Lojo, Martin Burtscher, Milind Kulkarni, Rashid Kaleem, Roman Manevich, Tsung-Hsien Lee, Xin Sui
Issue Date:June 2011
pp. 123-128
For more than thirty years, the parallel programming community has used the dependence graph as the main abstraction for reasoning about and exploiting parallelism in "regular" algorithms that use dense arrays, such as finite-differences and FFTs. In this ...
     
A q-learning based adaptive bidding strategy in combinatorial auctions
Found in: Proceedings of the 11th International Conference on Electronic Commerce (ICEC '09)
By Ho-Fung Leung, Xin Sui
Issue Date:August 2009
pp. 186-194
Combinatorial auctions, where bidders are allowed to put bids on bundle of items, are the subject of increasing research in recent years. Combinatorial auctions can lead to better social efficiencies than tractional auctions in the resource allocation prob...
