My main research interests are in the fields of Information Processing. Related topics include data mining, information retrieval, machine learning, pattern recognition... I'd like to help people get what they need more easily. Let the computer do more for us with less help from us, learn from experience, adapt effortlessly, and discover new knowledge. We need computers that reduce the information overload by extracting the important patterns from masses of data. And we need computer understand what we need. This poses many deep and fascinating scientific problems: How can a computer decide autonomously which representation is best for target knowledge? How can it tell genuine regularities from chance occurrences? How can pre-existing knowledge be exploited? How can learned results be made understandable by us?

My research addresses these and related questions. Research topics that I'm working on, or have recently worked on, include:
