PCA & ICA
16 April 2007I found a couple of interesting tutorials. One is on principal component analysis by Lindsay I. Smith and the second one is about independent component analysis by Hyvärinen and Oja. Good introductions if that is what you are looking for.

One talk and a visit to UK
8 October 2006September 21 I was invited to give a talk at the Computer Science Department at UIUC. During the talk “Combating User Fatigue and Contradictions in Subjective-based Optimization Schemes” I reviewed some of the research I have been involved about active interactive genetic algorithms. The PDF of the presentation can be downloaded here. I also gave the same presentation to some of the members of the ASAP research group at the University of Nottingham. Natalio Krasnogor invited me for a visit. The main topic was latest advances on Pittsburgh LCS (Jaume Bacardit is working there on protein folding problems using Pitt-style LCS). I really enjoyed interact with people there—lots of challenges and interesting discussions. Oh, I almost forgot, the three days I was in Nottingham I saw the sun most of the day :).
