The research team of the Pattern Recognition Laboratory, between a variety of skills, has a strong experience in Computational Intelligence Algorithms and their applications in many different areas, such as Bioinformatics,Economy, Medicine, Data Mining, Intelligent Agents and e-Learning. The latest years, the main effort was given to the research and development of multi-agent and adaptive e-learning systems. This work was supported form national funding and has resulted to a significant number of graduate Theses, Master Theses, a PhD Thesis and a significant number of publications. For more details see:
Furthermore, we have developed a pilot Adaptive Multi Agent e-Learning System (based in PHP, JSP and .NET platforms), that uses Computational Intelligence Techniques to predict the specific student reaction, during the exam phase. The historical data from the student’s record will be used, in the proposed research, in order to train the intelligent algorithms to adapt the content, provided by the system, to the specific user’s needs. This idea won the second prize in the Imagine Cup 2007 (Greek branch), among 18 other proposals from the Greek Universities.
