Our next speaker of the STRC seminar series will be Dr Athanasios Tsakonas. The talk will take place next Wednesday, 23rd of May in Lawrence Lecture Theatre at 16:00 h (please click for a map)
In my personal view, this is a very interesting talk for those of us working on any kind of predictive approaches. Please find below more details.
Evolving Simple and Complex Structures To Combine Predictors
The popularity of ensemble systems in real-world problems is a natural result of their effectiveness for a range of tasks, where single predictors or classifiers can overfit or provide weak solutions. A primary property in ensemble systems, contributing to their ability to generalize better is a combination of individual performances and diversity among individual learners. This lecture presents effective approaches for the generation of multi-level, multi-component combined predictors, through a grammar driven evolutionary framework. Several grammar schemes are presented for the production of hierarchical and fuzzy rule based ensembles. Candidate architectures are investigated in terms of data resampling, and different training approaches are tested, involving ensemble diversity measures
This is a short curriculum of our speaker:
Dr. Athanasios Tsakonas received his M.Eng in Electrical and Computer Engineering from the National Technical University of Athens and his M.Sc. and Ph.D from University of the Aegean. His Ph.D thesis was “Computational Intelligence in Complex Managerial and Financial Domains – The Evolutionary Neural Logic Network Paradigm”. Athanasios has gathered strong experience in the analysis, design and development of specialized computational intelligence systems, with applications in the financial and medical sector. His experience includes participation in European and domestic research projects (such as BOEMIE, SHARE, EUNITE, INFER, etc.), occupation of related research positions in top research centers (such as N.C.S.R. Demokritos) or in the private sector (banks, software development companies, etc.), as well as teaching related courses in universities (Aristotle University of Salonica, Demokritus University of Thrace, etc.). His research interests include computational intelligence, data mining, genetic programming and complex systems. He has published 1 book and more than 45 articles in total, in international scientific journals, conferences, or as book chapters. He is with the Smart Technology Research Centre, Bournemouth University, since January 2011.
