Prague Stochastic 2006. Proceedings of the joint session of 7th Prague Symposium on Asymptotic Statistics and 15th Prague Conference on Information Theory, Statistical Decision Functions and Random Processes
Prague Stochastics 2006,held in Prague from August 21 to 25, 2006, is an international scientific meeting that continues the tradition of organising Prague conferences on stochastics, established here five decades ago. Traditionally, the scope of the proceedings, as well as the conference itself, is quite extensive; the topics range from classical to very up-to date ones. It covers both methodological and applied statistics, theoretical and applied probability and, of course, topics from information theory. The printed part contains the plenary and invited papers, and the list of all contributions published in the volume. The CD disc, attached as an official part of the book with the same ISBN code, contains all accepted papers.

Fuzzy coalitional structures
Mareš, Milan ; Vlach, M.

Application of finite mixtures to text document classification
Novovičová, Jana ; Malík, Antonín
Finite mixture modelling of class-conditional distributions is a standard method in a statistical pattern recognition. We proposed to use the mixture of multinomial distributions as a model for class-conditional distribution for text document classification task. The vector document representations using a bag-of-words or a unigram approach are employed. Experimental comparison of the proposed model and the standard models was performed using Reuters-21578 database.
