Janez Demšar, PhD
Associate Professor

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.
