eunite 2003A Look Back


eunite 2003 - the European Symposium on Intelligent Technologies, Hybrid Systems and their implementation on Smart Adaptive Systems took place from 10 - 12 July 2003 in Oulu, Finland. It was the third symposium organized by the European Network of Excellence EUNITE.

The symposiums' aim was to show new developments in the so called Intelligent Technologies: fuzzy logic, neural networks, evolutionary computation and machine learning. The focus was on hybrid systems that combine two or more of these technologies and/or address issues on adaptivity, preferably with special interest to solve industrial problems. One objective was also to investigate Adaptive Intelligent Systems: systems that coordinate perception, reasoning, and action to pursue multiple goals while functioning autonomously in dynamic environments. 92 papers were submitted to eunite 2003 and 12 authors were invited to present a paper during the symposium. After the papers were reviewed by the chairpersons of the different EUNITE committees, 20 had to be rejected. The remaining 84 papers were presented in parallel sessions.

The Programme

In the opening session on 10 July at 9:00 h, the EUNITE co-ordinator Professor Kauko Leiviskä from the University of Oulu in Finland welcomed the 113 participants and introduced them to the symposium.

He was followed by Dr. Heinz Mühlenbein from GMD - Gesellschaft für Mathematik und Datenverarabeitung mbh, St. Augustin, Germany, who had a talk about Three Examples of Smart Adaptive Complex Systems.

The next speaker, Michael Berthold from Tripos Inc., San Francisco, USA, gave a lecture about Adaptive Exploration of Imprecise Data in Bioinformatics.

The Competition

The opening session was closed with the Award of the 1st, 2nd and 3rd winner of the 2nd eunite competition, which was again organised by the Technology Transfer Committee.

Winners of the international EUNITE Competition Honoured in Oulu

In this year’s EUNITE competition three teams have succeeded in predicting the temporal development of the five response signals in the process control of a glass melting trough (with 29 input parameters) over a period of two weeks. The - weighted - deviation of the modelled values from the real values under 1 %. The winners presented their results at the annual EUNITE Symposium from 10th to 12th July in Oulu, Finland. As an expression of its gratitude, Schott Glas awarded prizes in the amounts of 5000 € (1st place), 3000 € (2nd place), and 1000 € (3rd place). “We could not actually apply the concrete values from the prediction for plant control, perhaps because some decisive parameters had not yet been recorded, but the proposed model approaches are of great value to us”,

said Dr. Katharina Lankers, who had arranged the competition on behalf of Schott Glas.

EUNITE is a European association of scientists at universities and in industry; it is supported by the European Union with the objective of forming a network for excellence. EUNITE is dedicated to improvements in so-called intelligent, adaptable systems. The modelling abilities of the scientists are tested in an annual competition. The competition is coordinated by Jens Strackeljan at the Technical University of Clausthal, chairman of the Technology Transfer Committee of the EUNITE network.

The winners are Marcin Wojnarski at the University of Warsaw, Poland, first place; Dr. Bernhard Pfahringer at Waikato University in New Zeeland, second place; Dr. Dumitru-Iulian Nastac and Adrain Costea at the Computer Science Centre in Turku, Finland, third place. A total of twenty proposed solutions were received, some of them from the United States and Brazil, among other countries.

What was the problem posed for this competition? The data, 29 real input values as well as five real output values, each recorded at 15-minute intervals, were provided by Schott Glas, Mainz. These data were rescaled operational data for the control and indirect quality measurement of a glass melt over a period of fourteen weeks. The real physical meaning of these data was not revealed to the participants in the competition, since this, of course, is a company secret.

The measured values were supplied to the scientists in raw form; that is, they had not been pretreated or freed from interference, and noise was not suppressed. Thus, preparation of the data for modelling constituted a part of the given problem. The main difficulty was the frequent and in general unknown delay time of hours or even days between the variation of an input signal and the “response” from the glass melting trough.

During the last two weeks, only the real input values to the system, that is, only the control targets of the process engineers and the sometimes unexpected, but measurable external effects, were known to the scientists. The manner in which the melt reacts to these inputs was not indicated to the scientists.

The problem for the scientists was to predict the behaviour of the glass melt. Their predictions and the derived mathematical correlations between the input and output values were subjected to an empirical test by comparison with the real values. The time-weighted deviation of the process behaviour predicted by the winners from the real values amounted to less than 1 %.

The three winners have presented their results at the traditional EUNITE Competition workshop, which was very well attended by 25 participants. All three presenters used completely different approaches. The reports are available on request. To improve the exchange of different approaches and try to improve the current results we have established an open competition working group. For the kick-off meeting eunite invited three more participants which sent us promising ideas and started in a 6 hours workshop in Oulu. The results – and the whole group hopes that we are able to achieve an significant improvement- and the experiences with such a joined research activity should be presented during the next eunite symposium in June 2003.

Mathematical Simulation and Optimising,


General Assembly Meeting

The meeting was attended by 87 people. The Steering Committee was represented by its co-ordinators, Kauko Leiviskä and Karl Lieven, who gave an overview of the programme and asked Kauko Leiviskä to present the status of EUNITE. He explained that the project has meanwhile 166 members from 29 countries, which is more than expected. The seven running Task Forces were introduced as well as the Best Practise Guideline. Most of the Roadmap Work has been done in the committees and a summary report is about to be published in September 2003.

The introduction was followed by a presentation from Iain Russel, University of Wales, U.K. about “Monet: A Network of Excellence on Modell Based Systems”. He informed that the second phase of MONET has started in January 2002 and there are three different task groups in the project. These are namely the Automative task group, the Education and Training & BRDIGE task group and the Bio-Medical task group and their main aims were introduced. The project has meanwhile 70 nodes with 52 active members. Mr. Russell pointed out the benefits and gave an overview of the latest activites.

After this, a very lively presentation has been given by the winner of the SAS Award, Werner Brockmann from Medizinische Universität zu Lübeck, Germany. He explained his “Switched Pneumatic Electrical End Position Damping” and informed that the background was to develop new intelligent control methods like low cost pneumatic position control. He reported about the control problems, the pneumatic shock absorbing and their different methods and described the aims of the system and introduced the solution. The constructed product was shown in practise in a film, followed by a demonstration through a set-up of the end position damping. Finally, the conclusion was given and Karl Lieven suggested to put the demonstration on the EUNITE web site.

The full presentation from Dr. Brockmann will be available soon.

The future activities of EUNITE was the final topic of the General Assembly and the Administrator, Karl Lieven informed about the prolongation of EUNITE until September 2004. Furthermore, he reported about the future activites of the project, which are mainly the final symposium eunite2004 in Aachen, Germany and a 4th Competition. Jens Strackeljan told the participants about the planned Competition Workshop during eunite2003 and the idea to bring the people from the previous three competitions together. Jon Garibaldi informed everybody about the Bibliographical Database which is 95 % fulfilled and the Best Paper Award, where it is planned to invite the winner for a talk at eunite2004 at June 10-12 in Aachen, Germany.

Actually, the future of the EUNITE project had to be discussed at the Steering Committee meeting during eunite2003. Finally, Karl Lieven invited every participant to send new applications for interesting activities to the EUNITE Service Centre until the end of September 2003.
