Efficient Techniques for Relevance Feedback Processing (PhD Dissertation). To improve the retrieval effectiveness in multimedia database systems, relevance feedback is widely used for query refinement. Efficient evaluation of such iterative queries can be a challenge, especially when the multimedia database contains a large number of entries, the search needs many iterations, the underlying distance measure is computationally expensive, and there are numerous concurrent accesses. To address these issues, I have developed a generic framework, including index structures and query optimization techniques for efficient relevance feedback processing. My contributions are: efficient target search techniques, handling local optimum traps, supporting concurrent accesses, fast query processing for Support Vector Machines, and reducing the number of expensive distance computation for k-NN queries in multimedia retrieval. This project is being developed with C, C++, Java, MySQL, and Matlab.
YMon Metrics Storage Benchmark Project (2008 Summer Intern at Yahoo!). The monitoring infrastructure group at Yahoo! provides technology used by the rest of the company to collect large amounts of real-time operational data on a global scale with new metrics being added daily. In this intern project, I surveyed existing time series storage systems used within Yahoo! and available in the open source world, developed a prototype to achieve flexibility to add new metrics and perform ad-hoc aggregation, and scalability to store massive metrics data, and finally provided a recommendation about which time series storage to use. This project was developed with Perl and MySQL.
UCF-Symantec Storage Grid: A Service-Oriented Approach (January 2006 - December 2007). We developed the Storage Grid, a new-generation backup technology for Symantec. Most existing data backup systems adopt the traditional client-server model. However, this model has the following shortcomings: static resource binding, no dynamic load balancing, underutilization of some servers, and high administration cost. To address these limitations, we propose a virtual storage service with the following features: single-instance storage to save storage and communication costs, adaptor architecture to support heterogeneous backup applications transparently, data replication to enhance data availability, data redirection to avoid job resubmission, and intelligent scheduling to balance workload and storage usage among nodes. Our project has been selected to be presented at the Symantec Cutting Edge Conference 2007, and a pending U.S. patent has been filed by Symantec Corporation. This project was developed with C, C++, MySQL, RRDtool, and Perl. [PDF][PPT]
Imagesoft Archive System Migration Project, sponsored by Fiserv Imagesoft. We have successfully converted the existing Sybase-based Imagesoft archive system running on Sun Solaris to an Oracle-based system running on the Red Hat Linux, while maintaining full functionality, taking advantage of appropriate Oracle features.
