Feel free to download my PhD thesis entitled "Efficient Feature Reduction and Classification Methods: Applications in Email Categorization and Drug Discovery."

Watch out for our new book chapter "Utilizing Nonnegative Matrix Factorization for E-mail Classification Problems" which will appear in the 3rd edition of the Book "Survey of Text Mining" (by M. Berry and J. Kogan, eds)

Our new journal article "Comparison of Contemporary Feature Selection Algorithms: Application to the Classification of ABC-Transporter Substrates" has been published in the latest issue of QSAR & Combinatorial Science. This work is interdisciplinary work with the Group of Prof. Gerhard F. Ecker at the Department of Medicinal Chemistry

The link to this article can be found here.

Today I gave my presentation about our work entitled "E-Mail Classification based on Non-Negative Matrix Factorization" at the 2009 Text-Mining Workshop at the SIAM Data Mining Conference (SDM) 2009 in Reno/Nevada.
