Proceedings Article
Density-Based Clustering over an Evolving Data Stream with Noise.
TL;DR: A novel pruning strategy is designed based on these concepts, which guarantees the precision of the weights of the micro-clusters with limited memory, and demonstrates the effectiveness and efficiency of the method.
Proceedings ArticleDOI
Security and Privacy in Cloud Computing: A Survey
TL;DR: This paper investigates several Cloud Computing system providers about their concerns on security and privacy issues and finds those concerns are not adequate and more should be added in terms of five aspects (i.e., availability, confidentiality, data integrity, control, audit).
Journal ArticleDOI
Tracking clusters in evolving data streams over sliding windows
TL;DR: The exponential histogram is used to handle the in-cluster evolution, and the temporal cluster features represent the change of the cluster distribution, and a novel data structure, the Exponential Histogram of Cluster Features (EHCF) is proposed.
Proceedings ArticleDOI
Dynamically maintaining frequent items over a data stream
TL;DR: A new novel algorithm, called hCount, is proposed, which can handle both insertion and deletion of items with a much less memory space than the best reported algorithm, and is also superior in terms of precision, recall and processing time.
Proceedings ArticleDOI
Services in the Cloud Computing era: A survey
TL;DR: Six categories of Cloud Computing services are divided into six categories and detailed analysis to these services are provided, as well as those companies which provide the corresponding service categories.
