We present a distribution-based and transformation-based approach to synthetic data generation and demonstrate that the approach is very efficient in generating different types of multi-dimensional numerical datasets for data clustering and outlier analysis. We developed a data generating system...

Technical report TR01-12. Searching for frequent patterns in transactional databases is considered one of the most important data mining problems. Most current association mining algorithms, whether sequential or parallel, adopt an apriori-like algorithm that requires full multiple I/O scans of...

Technical report TR10-04. This paper describes a novel and fast placement algorithm for field programmable gate array (FPGA) design space exploration. The proposed algorithm generates the placement based on the topological similarity between two configurations (netlists) in the design space....

Technical report TR03-15. In this paper, we address the problem of protecting some sensitive knowledge in transactional databases. The challenge is on protecting actionable knowledge for strategic decisions, but at the same time not losing the great benefit of association rule mining. To...

Technical report TR04-17. Preserving privacy of individuals when data are shared for clustering is a complex problem. The challenge is how to protect the underlying attribute values subjected to clustering without jeopardizing the similarity between data objects under analysis. To address this...

Technical report TR01-06. We are so used to the ubiquitous World-Wide Web (WWW) that we take it for granted. There is no need to emphasize how dynamic, large, rich, and unstructured, yet important the Web is. From researchers and engineers to children and retired elderly, everyone uses the WWW...

Technical report TR04-07. Typical association rules consider only items enumerated in transactions. Such rules are referred to as positive association rules. Negative association rules also consider the same items, but in addition consider negated items (i.e. absent from transactions). Negative...

Technical report TR01-05. Web-based technology is often the technology of choice for distance education given the ease of use of the tools to browse the resources on the Web, the relative affordability of accessing the ubiquitous Web, and the simplicity of deploying and maintaining resources on...

Technical report TR07-03. Comparing groups or sets is the main focal issue in statistics, and data mining research has also focused on automatically identifying values and instances that differ significantly across groups, known as contrast sets. Whether traditional statistics or the work on...

Technical report TR08-13. The vast number of on-line biological and medical databases available can be a great resource for medical researchers. However, the different types of data and interfaces available can be overwhelming for many medical researchers to learn. Moreover, the available...
