The Great Pumpkin Patch is a seasonal attraction in Arthur, IL (just 40 minutes drive from Urbana). You can find all sorts of pumpkins and Halloween-oriented decorations. The gift shop is culturally interesting, and the home bakery has a wide variety of angel cakes (really soft and nice looking). The Great Pumpkin Patch also has one of the 1900s rural one-room classroom schools—there was at least one school in a 2 miles reach of any farm in Illinois....
September 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....
Recently I have been working on a data-mining problem that requires supervised learning. The problem is not supposed to be big, just a few hundreds of features. The interesting issue is the number of records, around half a million or more. Most of the implementations of supervised learning algorithms available on the web are not designed with such a volume of data. Scalability of the algorithms becomes a clear issue when dealing such a volume of data....
I have been using Kowari for a while. I am quite happy with it, but I am planning to ditch it in favor of the new release of Mulgara (Open Source for of Kowari) lead by Paul Gearon. If you haven’t check it out yet, take a look at it because is more than worth it. I have also been exploring other options. There is modified implementation of SPARQL for MySQL maintained by Eric Prud’hommeaux, his approach is very interesting one if you rely on MySQL server, it is a must....

Link to the PDF. Abstract Emotion is expressed by prosodic cues, and this study uses the active interactive Genetic Algorithm to search a wide space for sad and angry parameters of intensity, F0, and duration in perceptual resynthesis experiments with users. This method avoids large recorded databases and is flexible for exploring prosodic emotion parameters....
