Associativity in Combination of Belief Functions
Daniel, Milan
The nature of a contradiction (conflict) between two belief functions is investigated. Alternative ways of distribution of the contradiction among nonempty subsets of frame of discernment are studied. A new approach to understanding of the contradiction is used and an original notion of a potential contradiction is introduced. A new way of an associative combination of generalized belief functions is presented. A way of its proportionalization is suggested as well.

Financial Data Set Analysis - Hierarchical Testing with GUHA Method
Coufal, David
A structure analysis of financial data set released within PKDD'99 discovery challenge. The aim of the analysis is to design a decision tree, which can be used either as structure description of analyzed data or for prediction of certain, from banking point of view, interesting, facts. In a design process of a tree, the GUHA method is employed as a main part of here proposed hierarchical testing algorithm. The experiments show that this algorithm is reasonable and applicable well with good results.
