Padesátéosmé setkání Pražského informatického semináře

Radim Jiroušek

From Graphical to Compositional Models

'Bill Gates, the richest man in the world, loves Bayesian networks.' This statement appeared in the titles of many newspaper and journal articles after October 28, 1996, when the Los Angeles Times published an interview with him. He said that Microsoft's competitive advantage was its expertise in Bayesian networks.

'Bill Gates, the richest man in the world, loves Bayesian networks.' This statement appeared in the titles of many newspaper and journal articles after October 28, 1996, when the Los Angeles Times published an interview with him. He said that Microsoft's competitive advantage was its expertise in Bayesian networks. This declaration indisputably contributed to the popularity of Bayesian networks, and since that time, they have become a standard technique incorporated in statistical and data-mining software packages. However, Bayesian networks are only a part of the technology developed to handle multidimensional probability distributions efficiently.

The lecture will therefore also mention other, less famous, graphical models, as well as non-graphical tools, especially, compositional models. It will also show that most of the results valid for probability may be extended to other uncertainty theories, especially to belief functions. Thus, the audience will learn how to differentiate between combination and composition, and, for example, what belief functions have in common with the furniture sold by IKEA. The talk will be an author's subjective glimpse of almost 40 years of history and an opportunity to recollect some names that should be remembered.

Radim Jiroušek

Radim Jiroušek is a student and follower of the distinguished scientist of Greek origin, RNDr. Albert Perez, DrSc. Jiroušek graduated from the MFF UK (1969) and received academic degrees from the Academy of Sciences: CSc. (1979) and DrSc. (1993). After completing postgraduate studies, he accepted Perez's offer and commenced a research career at the Institute of Information Theory and Automation (ÚTIA) of the Czechoslovak Academy of Sciences. After 1998, he participated in forming the Department of Mathematical Decision Theory at ÚTIA, which he afterward led for more than five years. He also started teaching at the Czech Technical University in Prague and the University of Economics, Prague, and served in different academic positions for nearly twenty years at the latter. The international professional community knows Radim Jiroušek primarily for publications concerning the representation of multidimensional probability distributions and later for his theory of compositional models. He is the author or co-author of more than a hundred and fifty publications. His name is also connected with Workshops on Uncertainty Processing (famous WUPES), which have been organized since 1988. He also participated in the realization of several international projects. He was the local coordinator of three European projects within the fifth and sixth framework programs and the ESF EUROCORES project, The Logic of Causal and Probabilistic Reasoning in Uncertain Environments.

O PRAŽSKÉM INFORMATICKÉM SEMINÁŘI

Seminář se obvykle schází jednou za měsíc ve čtvrtek v 16:15 a to buď v budově FEL ČVUT nebo v budově MFF UK.

Jeho program je tvořen hodinovou přednáškou, po níž následuje časově neomezená diskuse. Základem přednášky je něco (v mezinárodním měřítku) mimořádného nebo aspoň pozoruhodného, na co přednášející přišel a co vysvětlí způsobem srozumitelným a zajímavým i pro širší informatickou obec. Přednášky jsou standardně v angličtině.

Seminář připravuje organizační výbor ve složení Roman Barták (MFF UK), Jaroslav Hlinka (ÚI AV ČR), Michal Chytil, Pavel Kordík (FIT ČVUT), Michal Koucký (MFF UK), Jan Kybic (FEL ČVUT), Michal Pěchouček (FEL ČVUT), Jiří Sgall (MFF UK), Vojtěch Svátek (FIS VŠE), Michal Šorel (ÚTIA AV ČR), Tomáš Werner (FEL ČVUT), Filip Železný (FEL ČVUT)

Idea Pražského informatického semináře vznikla z rozhovorů představitelů několika vědeckých institucí na téma, jak odstranit zbytečnou fragmentaci informatické komunity v ČR.
