I started working at the Laboratory of artificial inteligence
after graduating in 1996. I teach several courses at the Faculty of
Computer and Information Science, while my main occupation is research,
namely various data mining methods. My venture point is machine
learning, but lately I am especially interested in visualization as a mean of clearly conveying information to the user or
data miner. I apply my research mostly in the fields of medicine and
genetics.
I spend most of my time programming an open-source component-based system for machine learning and data mining Orange. I was also involved in theoretical development of an inteligent assistant for discovery of genetic networks from mutant data GenePath.
Education
I studied computer science at the Faculty of Computer and
Information Science in Ljubljana, where I received BSc degree in 1996,
MSc in 1999 and PhD in 2002, all under mentorship of prof. Dr. Bratko
and co-mentorship of prof. Dr. Blaz Zupan. The area of the dissertation
was artificial inteligence, in particular function decomposition, a
method for data-based constructive induction without a predefined set
of operators.
