Presentation: Open Source Softwaresystem HeuristicLab

There is an official HeuristicLab presentation scheduled on September, 30th at the Upper Austria University of Applied Sciences (FH OÖ), Campus Hagenberg. The event will start at 16:30 with a welcome drink and will include a presentation of HeuristicLab and some of its applications. There will also be a buffet afterwards.

Consortium Meeting

Prim. Dr. Herbert Stekel, MD, from the General Hospital Linz (AKH Linz) was so kind to organize the last consortium meeting before the summer. Shortly before 3:00 p.m. the Heureka! project consortium met in front of the Ars Electronica Center (AEC), which is also one of the most important sights in Linz. Gerfried Stocker, CEO and artistic director of the AEC, surprised us with an exclusive and exciting tour through his "Museum of the Future", followed by presentations and a buffet in the Sky Media Loft. In detail, Heureka! researchers presented results on the following topics:

  1. Research group head Michael Affenzeller talked about the interim evaluation of Heureka! and briefly sketched the most important accomplishments of the center in the last 1.5 project years.
  2. Stefan Wagner talked about the HeuristicLab 3.3 release and gave a live demo of our greatly improved software framework. You can get more information about the framework on the HeuristicLab Develeopment Homepage.
  3. Finally, students from FH OOE presented the results of their study project about medical data analysis in cooperation with AKH Linz.

Michael Affenzeller would like to thank AKH Linz for hosting the meeting and all consortium members for attending!

Heureka! Film Spot

We recently had a film team in Hagenberg for a short portrait about our work in Heureka! The resulting film was presented at the 4th Science Symposium of Austrian Universities for Applied Sciences in Pinkafeld, Burgenland and very well received.

First Place in Symbolic Regression Competition

We are proud to announce that team HEAL achieved the first place at the symbolic regression competition of the EvoCompetitions side event of Evo* 2010. The goal of the competition was to create a prediction-model for a variable that is expensive to measure based on 57 other variables that can be easily measured based on data from a real world chemical process.

In the modeling process we tried to find a simple model that can be readily interpreted and validated by the domain experts. We put more emphasis on the interpretability, the prediction error of our final model is thus relatively large.

To generate the models for this competition we used an internal pre-release candidate of our software framework HeuristicLab that will be released real soon now. The fact that we achieved first place in this competiton and also second place in the financial time series competition shows that HeuristicLab is powerful and flexible enough to achieve competitive results for real world applications with minimal preparation effort.

Finally we would like to thank the organizers of the symbolic regression competition and of the financial time series prediction competition for making the datasets available for reseach purposes and the EvoCompetitions chair Anna I Esparcia-Alcázar for the organization of the event.

Second Place in Financial Time Series Prediction

Team HEAL achieved second place at the financial time series prediction competition of the EvoCompetitions side event of Evo* 2010. The goal of the competition was to prognose the future values of ten financial time series for a horizon of ten time steps. We used HeuristicLab and genetic programming to create our forecast.
