Symposium on Imprecise Probabilities and Their Applications July 20-23, 2005 - Carnegie Mellon University <http://www.sipta.org/isipta05>http://www.sipta.org/isipta05 Highlights: - Invited talks by Arthur Dempster and Isaac Levi - Tutorials by Gert de Cooman, Paolo Vicig and Kurt Weichselberger on the afternoon of July 20 - 46 technical papers will be presented (oral and poster) on July 21-23 - Workshop on Financial Risk Assessment, on the morning of July 24 =================================================== The ISIPTA meetings are one of the primary international forums to present and discuss new results on the theory and applications of imprecise probabilities. Imprecise probability has a wide scope, being a generic term for the many mathematical or statistical models which measure chance or uncertainty without sharp numerical probabilities. These models include belief functions, Choquet capacities, comparative probability orderings, convex sets of probability measures, fuzzy measures, interval-valued probabilities, possibility measures, plausibility measures, and upper and lower expectations or previsions. Imprecise probability models are needed in inference problems where the relevant information is scarce, vague or conflicting, and in decision problems where preferences may also be incomplete. The program with all tutorials, sessions and invited talks can be found at the site of the symposium (<http://www.sipta.org/isipta05>http://www.sipta.org/isipta05). The site also contains information about the conference venue, housing and transportation, and on-line registration. Workshop on Financial Risk Assessment ------------------------------------- There will be a workshop addendum to the conference, to be held on the morning of July 24, with invited speakers on the topic of financial risk assessment, to which all of the ISIPTA'05 participants are welcome, at no additional registration cost. The list of invited talks to be presented at the workshop can be found at the symposium site. Steering Committee ------------------ Gert de Cooman (Universiteit Gent, Belgium) Fabio G.
