Lecture Course on Graphical Models at University of Helsinki for Oct-Dec. 2005. Lectures in PDF are available as L1, L2, L3, and L4.

My Docentship Lecture given at the University of Helsinki, 6th February, 2006 (in PDF and in Postcript, 2up, gzipped).

Source code for Multinomial PCA available on request. Its GPL'd and runs on 2Gb of text in a few days on your desktop. Comes with a custom browser to inspect results. See MPCA Page and published on Freshmeat.NET.

Some older activity:

• Web-Based Adaptive Personalization (for an IJCAI workshop)
• IND Version 2.0 - creation and manipulation of decision trees from data, my first research programming project.
