TITLE: Current Research in Machine Learning and Text Analysis at the University of Ottawa
AFFILIATION: School of Information Technology and Engineering (SITE), University of Ottawa
DATE: Monday 13th September 2004 (Please note unusual date/time)
TIME: 1pm - 2pm
PLACE: CSE K17 1st Floor Seminar Room
The presentation will review current research projects in our Text Analysis and MAchine LEarning (TAMALE) lab. These include a) privacy-oriented data mining and privacy-enhancing technologies b) feature selection with the focus on Inductive Logic Programming c) applications of data mining in Software Engineering and bioinformatics. The Lab is also involved in a broader research initiative in Electronic Commerce. We will present the lab, outline all of the above research, and focus on the current work on feature selection. We will argue the need for a feature selection-like process in ILP, present the difficulties, and describe our unique approach. We will show how the feature selection task becomes an instance selection task, how the latter can be reduced to a feature selection problem in a propositional multi-instance setting, and what are the challenges for the latter problem, specific to our research. We will present our current solution, empirical results we have obtained, and the work in progress.
